"Maybe he's also wearing a hat" 😂😂 that's why I love Khan Academy.
same here ;)
+Akash Cherukuri I agree
Katy The Great ;)
Ditto
TheCosmoBros same
I'm currently doing online school. On my first 2 exams I made about a 65 on both of them. No teaching is going on I'm just reading from an online textbook. I watched videos of yours for 3 hours and made a 90 on my 3rd exam. Thankyou. You are teaching things that people will need for years to come
Is it My Ep Assignments?
All these people arguing about religion and I'm here trying to get prepped for the mcat
Studying for a Clep test to get into nursing school here . You guys want to open a clinic sometime?
kento2d9 I know right
wrong place...go see kaplan....
Religion is old-age stuff, it musn't be in under scientific videos.
Yes! I take mine in 2027 :) hope you’re doing great.
So your channel covers Biology,Chemistry, Physics, Maths, History etc. I've always waited for an Art section, but I now see why you've chosen to leave that subject out ;)
One thing I love about UA-cam and Khan academy is that not only can I go back and learn what I missed instead of having have too look stupid asking questions to a teacher but, a teacher who actually takes the initiative and time to educate ppl, because I know I hated asking the teacher to go back because of missing some details, and struggling to go back school to learn whatever i left off at and not only just one subject but all subjects . I'm forever appreciative of this page!
This was one of the first videos I've watched from the Khan Academy. Now, 4 months and almost 1100 videos later, I came back to this. What the Khan Academy has done for me is amazing, the amount of things I've learned is more than my whole high school experience. Sal Khan is my biggest inspiration and his work is truly amazing. Thank you for teaching the world.
If you value your sanity, don't scroll down.
I've already lost hope in my sanity so might as well 😅
😅😅😅😅
😂😂
Don’t worry, natural selection will deal with these kinds of people someday
Thank you for this
Good job, Sal!
Most of the videos explaining evolution you find on youtube are very complex, fast paced, confusing and use a very complex, scientific language. This is a very calm and thorough explanation, and I'm sure many will understand and enjoy it!
This guy, Sal, is brilliant. I am immensely grateful to this guy. I have seen 2 or 3 other videos on natural selection but to no avail. I had no idea about anything of biology before, therefore, it was really hard for me to understand the nuances here and there. But this guy has the special ability to walk laymen through these intricacies in such an easy way. 😍
"It's a really smart idea to become black!" - Best quote 2015

This video came out in 2009 but i totally agree. Best quote 😂💁🏽♀️
Johny Bender jajajajajajajaja
@Yashua Fradkin ikr 2020 went downhill fast

Your drawing skill brought the entertaining aspect to people studying the DAT. Thank you. :)
"uh... maybe he's wearing a hat!" Nice save dude!
I ended up getting an A! You literally helped me so much in my first year! cheers man!
I don't know who are making korean subtitle, probably korean.
I tried watching this, my english is so poor. thank you for that.
00:49 "that's the ape..mabye...mabye, he's also wearing a hat"
Why do i find that sooo funny?
I just recently became interested in science, particularly evolution. It's all because of my obsession with science vs religion and wanting to seek the truth. I remembered taking biology and physics in school and somehow passing but not really having the interest or desire to retain the information. And now that I'm fascinating with wanting to know more, I came to this video. And I'm so happy that Khan Academy that there are organizations like Khan Academy that provide all of this information for free. It's amazing.
***** I've read the bible. Not a christian. Science and reality is wayyy better for me. Thanks tho
Mythology is not everybody's cup of tea !!!
TaelurAlexis - you show evidence of latter-day consequences of how evolution has enhanced the abilities of the human brain. Keep asking!
Bob D Thank you Bob:)
Okay, I'm a little late to the reply party but here we go. I love Khan Academy. I love science (my majors were both mathematics and environmental science). And I love God. My dad's an architect and my mom's a nurse and they both drilled hard studying in all subjects and knowing biblical truths so I never had this "issue". One of my biggest pet peeves is this weird American belief that concepts of science and religion (specifically Christianity as we are in America) are enemies of each other. They're not. There is a reason a lot of early scientists were Christians including Darwin and to this day many current scientists such as Francis Collins (Former Director of the National Human Genome Research Institute and author of the book "The Language of God") are still Christian. There was never a conflict between the two, only conflicts between different groups' dogma (between both scientists and theologians alike using theories to shoot facts instead of facts to shoot theories). In fact, the bible is persistent with telling people to seek knowledge (ex. Proverbs 18:15, one of my favorites says, "An intelligent heart acquires knowledge, and the ear of the wise seeks knowledge.").
TL;DR
Evolution does not conflict with God's existence. You can love both. Hardcore creationists and evolutionists twist facts to prove their points so please make sure you study hard in both your scientific and biblical research (historical documents backs up Jesus' existence) so you can know the truth for yourself and not base it off of the weird beliefs people spew from their mouths.
Same here. I'm pretty much flying thru college with ease cuz i watch his videos FIRST, then listen to the lecture afterwards, and everything makes more sense since i'm building upon the intuition that Sal taught me.
I got a bit dissapointed when i got to know that evolution is random😕 i always visualised it to be something as a very unearthly force making living beings move according to their interests
I guess i need to go and cry now
I believe that there is a creator God, and that our purpose is to serve Him. What is your belief, and how would explain evolution to someone that doesn't agree. Please no that I hold no judgement, and if you would like me to share my beliefs more I am willing. If not I understand. Please no hate. I'm just curious and trying to learn more about the world around us.
The most understandable video on natural selection I have seen.Thanks!
I love how he says dude and dudettes. :D
@William Pinero yes
@William Pinero yes
In 2020 my teacher made me see this video, that was published in 2009.
Hi im a new youtuber
Please check my chanel i will share lots of intresting things
With only clicking the sub button you can help me alot
These videos are great, I can learn and shit at the same time.
Thank you Sal, particularly for this. Your online courses are super.
Evolution is fundamental biology and it's refuters are a serious hinderance to planetary progress, liberty and understanding.
I love that you use "natural selection" and "variation" to defuse and disarm the creationist noise.
Saw you on CBC News. Thank goodness. I'm going into senior year and whenever I don't understand something I might just go on here and look up some of your videos! Thank you so much. :)
Those pictures were adorable
I'm an international health science student in an American university and i have lots of question which i can not find the answer in my book. And i can not afford to get premium memberships of teaching websites. So, i really deeply appreciate your channel and your time you dedicate to these free videos🙏🙏🙏 you are helping me in my lessons incredibly! Thank you🏃♀️💕
ask your professor THATS WHAT THEY ARE THERE FOR!
Thank you for making my studying so much easier and fun ,i love your videos !!
I just have to say whoever made this channel is/are the BEST. Every single video on this channel that i've watched are explained the best way possible in entire youtube. Videos in this channel never fail to help me understand things fully. Makes my life soooo much easier. Thank you so much for this channel😊😊😊😊
Really interesting and helpful, thx!
its so helpful! thanks khan :*
and even in 2022, it's still useful.
Literally watching this before my biology test tomorrow! Thanks, I have a clear understanding of what it is!
How did you do
I really love the way he teaches and lectures, every topic just becomes really interesting. ❤👌
Maleeha Aamir do you study in 11th class
ahahhahahh i love this video.. the way you talk doesnt make me feel like such a dumbass
Thanks a lot for the video. Now i completely understood what evolution through natural selection really means. Really appreciate it.
Me watching this video for a research about evolution 14 years after this video was posted.
I would say that until you understand biochemistry, you can not understand evolution in a deep sence.
In biochemistry, there is no difference between micro and macro evolution, there is no design, there is no purpose.
There is only colliding chemicals, following a few simple laws of physics.
And the "Psudo random" product of that, is what evolution is all about.
***** You then use the premise that evolution is a random prosess. I would look at it like this:
Evolution only builds on what works, and then expands on that until something new and even more adaptive comes along.
The probabilites you are describing are not independent, but every singel event that happens in the cell, is dependent of what happened before. Reducing the probabilities to a more humanly understood level.
From probability mathematics, you have:
p(A/A) = 1. (Probability of A occuring, given that A has occured) = 100%
No matter how unlikely something is, even if A = 0,00000000000000000000001%. It will happen, given that A allready has happened. This is how evolution works too.
My argument still stands, and you my friend don't know enough about evolution to claim things like that.
thats the deception! taking proven micro evolution and use that as a false proof for exxagerated macro evolution. they are 2 different things, its interior design vs expansion. DNA also shows that its a language. macro evolution is a marxist science.
+Hakon your "arguement" is baseless. colliding chemicals are hardly simple, but even natures of 2 are different as 1 needs mutations, most are cancerous. it doesn't change facts it speciation/macro, isn't a real seen science ever in multi cell organisms, but a guess work!
7:46 "It looks like a really smart thing to do, to become black..." Hell ya!
w e c a n l i v e l o n g e r
these videos are amazing.. i learn more on youtube than i do in class..
I just wrote a biology csec exam and the exact scenarios of the peppered moths and the antibiotic resistant bacteria questions came up. I watched this video last night and was able to remember this so easily man.. thanks a million sal I truly love u man :')
"ALRIGHT lets learn!!" -I said
THEN
the hat thing derailed my train of hat thought
@3:00 he's referring to "Lamarckian inheritance" to be precise. Either the term itself, or his name "Jean Baptiste Lamarck," will likely be on your first Exam for Evo.
I'm glad there's some context to the drawing @2:20. Without context, it seems quite perverted.
Excellent Mr. Sal, very simple and clear explanation. Hats off !! to you
so clear! thank you!
I plan to be a biologist and that's what I'm taking in college this year, and my cousin showed this to me and I believe this will help tremendously! Thank you for the vids!
How are you doing with that?
The thing is that religious people don't understand is that this is no matter of belief, it's a cold hard fact.
a cold hard marxist "fact" lolz even your bishops& rabbis like dawkins use terms like intel design as dna is a language. your fossil frauds are like x-men concepts, except they don't spread it on million generations to hide from burden of proof.
It's a matter of faith and guidance through our savior.
Tony Soprano this is pure Bolognese, food for the week mind
Tony Soprano Actually it’s called a cold hard theory
I would be willing to give anybody a thousand dollars if they could find ONE COLD HARD FACT that supports the (fiction) story of evolution.
None exists.
Thank you so much for these videos!
what a fantastic tutorial!
@Herman Tam
i don't know for sure but i think evolution will be almost universally accepted eventually in the future. just as it took the roman catholic church hundreds of years after galileo to accept that the earth goes around the sun, and among other things, i feel evolution will eventually have it's place even in most religious beliefs. even the pope and the church today accept evolution
Raymond ... but scientists do not believe in evolution and the scientists worldwide are forming creation organizations to expose the atheistic professors who promote their fiction story of evolutionism
@@danminer5343 Sources?
@@chaosd5239 - you will not find this in evolutionary propaganda sources for obvious reasons. The most educated scientists know that there is nothing known about evolution thus there is nothing to believe except stories that do not show how evolution could be possible and there is no evidence for evolution. Evolutionism is nothing more than a failed attempt to explain away the reality of our Creator God who created us. You can show me that there is zero science supporting the story of evolution by your inability to find any evidence for evolution. I dare you to try.
@@danminer5343 yeah. I just asked for sources. And while I could make a decent sized list of evidences for evolution, I'm not gonna engage in an argument. I've learned that online arguments never go anywhere and are pointless.
@@chaosd5239 - You made a false statement. I have studied this issue for decades and have read many hundreds of books, journals and publications and challenged many evolutionists to present ONE HONEST SCIENTIFIC STATEMENT that would favor a belief in evolution. Fraud is not science. It is impossible for you to find any evidence for evolution since none exists. I would show the fraud in any you would present.
I am a Christian and I don't understand why everyone always gets so butthurt about evolution in regards to the bible. Just think of evolution as how God creates life.
zanocco641 Here's why. Some people take their religion very serious. Seriously enough to actually read their Holy Doctrine and believe it happened way their circular reasoning Book of proof said it happened, not by evolution and natural selection over billion of years. This Christian God you follow must be a new God all together. Evolution completely destroys the Adam & Eve creation myth/assertion, which destroys the absurd "original sin" concept, thereby destroying the illogical & shockingly absurd "need" for God to impregnate a woman with himself in human form, so he could sacrifice himself to himself to act as a loophole for rules that he created in the first place that he could not circumvent.
Only cognitive dissonance, not reading the bible, and/or recreating a new individualistic & highly subjective version of Christianity in one's own mind (like most Christian's nowadays do anyway) could ever make these two contradictory premises of Christianity and Evolution at all compatible. Telling yourself that God used evolution is a presupposed conclusion, which is a logical fallacy, but you have no way of linking evolution to "God did it" outside of your mind, or even that it even points to the existence of a God, or is even possible. Evolution shows how life can evolve without requiring any intelligence. It's just beyond the understanding of most human minds to grasp as well as uncomfortable harsh reality that's not very comforting to their psyche, unfortunately, because most people, especially in American have not been taught how to think critically for themselves, or simply allow their emotional preconceived, usually indoctrinated convictions to overwhelm their logic & critical thinking ability. Most are just indoctrinated slaves of their own minds simply due tot their inherited culture where most have not or simply do not exercise their critical thinking skills in this area at least simply because so badly they want to believe, because they want to believe.
FreeThinking Atheist the bible is filled with symbolism. Of course the Adam and Eve thing isnt accurate in any sense. All I care about in this world is just letting people do what they want to do unless they are threatening the lives of others because then said people need to be dealt with in some way. Arguments about religion are circular and only cause unnecessary conflict, Someone else can believe what they want, and if it differs from mine, So what? Believe what you want to believe is my point, and both theists and atheists just need to kinda stfu and quit complaining about others differing beliefs, at least on the internet on a fucking biology help video.
prove god, and I will entertain a god built world. Hey jesus man.....where the hell are you? no response, hardly an answer
+free in theory one could say evolution effected all except humans, but its wrong, macro evolution is just marxist science, its like the x-men but spread of million generations to avoid proving it and they mix it up with micro evolution in conversations just to deceive. macro evolution so far only takes place in single celled creatures.
zanocco641 is
You exlpained it so good, thanks !!!
Cool videos!You explain very simple!
2:02 - arrow to the knee
you gotta love how Khan made a reference to the Columbine massacre with this video!
Eric Harris: Natural Selection
I'm coming late to the discussion, but the only thing I disagree with is the randomness of the process, is that all of it happens by chance. I'm not saying that organisms, much less monocellular organisms, choose to evolve. I'm saying that this isn't randomness and chance, this is Nature, thus natural selection, and Nature isn't governed by chance alone. There are a lot of mechanisms happening in Nature that humans still can't, and maybe will never, understand.
A lot of things seem to be random, including genetic mutations and variation. There are certain principles in quantum mechanics that seem to be inherently random, such as the wave function of a particle only giving you the probabilities of a particle's position and its speed.
I mean when you roll a dice its not exactly random if you look at it in the meta level but that is not how random is being used when talking about it.
@KhanAcademy Thanks for explaining so thoroughly
thanks a lot sir, for making those videos,its really helpful......
From INDIA RTMN University....
Tell them to stop praying to cows in India and watch Khan academy
What????
Oi!
*looks for religious Flame War*
What anime is your profile pic from?
Thentacle hi
What anime is your profile pic from?
Thanks so much for this video. It is explained very simply and even my younger students were able to grasp the concept.
Thank you so much. With respect .
fucking fascinating
Vsauce should take notes
lmao u did not
"Gee,I would like to get to those apples"🤣🤣🤣
hello, I have a question, is it possible, after watching only these lessons of the khan of the academy, to take sat. I am a foreigner so I ask
I love this explanation. Thanks
Evolution is very fascinating!
Ugh.. I already knew what to expect in the comments, but silly me, I looked anyways.
I always find it amusing that while (usually) every Average McDumbass is content to shrug accept (or rather ignore) developments in say, pure Chemistry or Physics and say "Well, I don't really know much about that", the moment their creation myths seem threatened they're suddenly fucking experts through sheer intuition, capable of shattering the core pillars of decades of Biology with unimpeachable rebuttals that only took them mere seconds to formulate.
Amen my brother
evolution is a unseen marxist science as a whole based on deceit. micro evolution is generally accepted, but the macro evolution x-men fantasy of speciation which evolutionists put over a million generations to avoid the burden of proof isn't.
Apes don't have tails. I thought you were a teacher :) jk jk you're a lot of help thanks
There is always variation in a population (meiosis) and the environment selects for traits. Macroevolution occurs over millions of years and microevolution occurs in a shorter time frame. An example of macroevolution is the extinction of dinosaurs. Through adaptive radiation, the once fragile mammals conquered the earth and the environment selected for successful traits in their biomes. An example of microevolution is pesticide resistance, since meiosis (in a rapidly changing organism) lead to the selection of pesticide resistance.
Thanks, That was awesome.
Believe in evolution or not just understand and memorize it to pass the SAT
SAT doesnt include science just Math and English
Beleive in? YOU CANNOT BELEIVE IN EVOLUTION. It's a scientific fact -not a belief stuff- and you MUST accept this --even you don't want to.
Memorizing does not provide you learning.
Apes don’t have tails 😂 🤦♂️
Daniel Lopes that’s an evolved ape my guy did you not see planet of the apes?
He fixed it on his next video lmao
Mr. Khan, thank you for uploading these videos and spending your precious time to promote free education. Your work is invaluable and highly appreciated. - junior in college
I had my exam today and wanted to thank you! Despite the fact that the paper was ridiculous as it excluded a lot of main subjects i.e. immunology and DNA and included a lot of subjects that we weren't essentially taught in class. But anyway thanks a lot
Can't atheists believe in evolution and not ridicule Christians, and can't Christians believe in God and not ridicule atheists! If someone wants to believe something, he or she should have the freedom to do so without being taunted.
What do I know I'm a snail.
Evolution requires no belief.
Evolution is a belief in the facts supporting the theory. All of science is a belief system since science is not absolute. We are not omniscient, and science is constantly changing as our knowledge base expands. The difference is that science is a systematic approach and study.
It is false to say that science contradicts religion and vice versa. No evidence has been given to support either side as proving the other false. Evolution for example, is not the proof that God does not exist (in fact, it heavily suggests the concept of God as it points that species branched out from a single source). That said, relgion is beyond our current means of study. For this reason, science is agnostic. To be atheist means to not be scientific, but to be religious as you have the belief in the denial of religion, without any unbiased factual evidence.
Sarcastic Nerd Evidence.
pimpekfun I think you can be a Christian and believe God crested people and animals but that natural selection with animals still happens. God created science you know?
Saad Rizvi where did he sad that?
There shouldn’t even be any arguments about this. Creationists actually believe in a bearded sky fairy rather than FACTS. I’m not saying facts out of ignorance, I’m calling them facts because they are proven. Believing in one religion is believing in a few out of millions of hypotheses versus a couple theories/ facts. Why believe in magic when you can believe in reality?
It's not magic. It's faith, however, the bible can be very scientifically proven.
Digital Math
Then why isn’t it proven?
Here's for one instance, a particularly small one, but i like to think about all the little things...Today's year is 2018, correct? But when did people start numbering years? It's when Jesus died on the cross and was resurrected, 2018 years ago he died. Julius ceaser (idk how exactly you spell his last name) died March 15, 44BC, even before Jesus, but how come no one ever doubts his existence?
A Person ... and all evolutionists believe that nothing created everything even though there is zero evidence for evolution, not even one shred of evidence, only a imaginary story that disagrees entirely with science, yet deluded fools still try to believe it. Evolutionists believe that magic created all complex organisms that could not live unless they were created already containing all required parts and systems so that they could live and reproduce.
@@danminer5343 What do you mean by "not even a shred of evidence"? There are multiple evidences of evolution in Biology, Chemistry, Mathematics, Archeology and other sciences such as Geology, while the only "evidence" of God is a 2700 years old book.
Sal khan,one of my favourite person I have ever see.
I like they way he says dude. Nice video thanks dude :)
@77davidwebb
evolution doesn't say that life came form the big bang, or even how it formed. it simply deals with how life changes over time, with extreme accuracy. and how would any holy book in the world have automatic authority?
***** if you want to learn more about the big bang, then watch Lawrence Krauss: A Universe from Nothing. he explains why there is something rather than nothing and why nothing will give rise to something. Besides, earth biology only deals with life n earth, not big bang cosmology.
"Yet, you still can't find any evidence of a missing link"
You're right, because there is no missing link. We have a pretty comprehensive fossil record showing progressive evolution from ape to man (and other species). It doesn't matter what religious retards believe, they have always been against genuine knowledge from the very start.
fossils are commonly frauds & guess works with millions of years of gaps, its like the x-men art concpet except the real world marxist evolutionists spread it over millions of generations to hide from the burden of proof!
false sects like shia are judeo made No, fossils are the physical representation of the mutations, and we can actually see where the species split off into two, as well as we can observe the gradual development of characteristics we see today. However, it isn’t the only evidence, not even close. We also look at the DNA of two species. The ONLY known mechanism for sharing DNA is through reproduction. There’s no other way for two species to share DNA, than through reproduction, which we can observe. You may say that, “god made it that way,” of which of course you have absolutely no evidence, and rather are just implementing the god of the gaps fallacy, which is worse in this case, because there IS an actual known mechanism. We have also observed speciation, where one species diverges into a difference specie. Creationists like to use the word “kind,” and yet they cannot even define what a kind is. They also love to distinguish between micro and macro evolution, and try to make them seem like different mechanisms, which is funny, because they haven’t done a shred of research to have come to such a conclusion justifiably. They are the SAME mechanism, in that the mutations are different. The only difference between the two is self explanatory; it is the time scale that they take place under, macro being large, and micro being small. Clearly you listen to Kent Hovind or some other religious dolt who has no idea what they’re talking about. Kent Hovind bought his pHD from a unaccredited institution, and held off from revealing where he taught for as long as he could, because he never taught in a single public school, rather only in church schools that he usually founded himself. He is a convicted fraud who doesn’t have a shred of expertise. Do not argue against evolution until you have the knowledge to do so. Every religious person I have ever met has been utterly ignorant to science as a whole, because they are willfully ignorant, and are taught to not trust anything anyone says other than the church, because they will see the idiocy of it all otherwise.
the Holy Book(BIBLE) is the Word of God.
*God,the creater of our world.*
so God's words are like commands for the world to follow.
just think of it as a user Manuel given by the Maker of the product that comes with the product..
without the user manuel you will screw up....
1:16 why is one dude watching the other guy pee from his butt?
Your drawing is so cool!
Omg you should seriously be my professor! I seriously learned from you way more than from y prof. you are hilarious & adorable lolz. thanks for clearing up what's evolution and natural selection is !!!
"Evolving."
-thinks of Pokemon-
Some of you came from Schoology and are reading the comments hi guys
I'm from all in one easy peasy
I love this channel!!!!
The dude said do-do😂😂😂😂
I swear to god this guy knows everything.
damnnn I am so angry at youtube...
Why didn't this pop up when I was searching for it last term :(
Science and Christianity go hand in hand. (Science is just understanding God's work.) I don't follow the latter due to how I feel about it, but with all of the evidence behind it. Why follow something based on a feeling if it has no grounds on reality? That would just be living a lie because of the feeling it gives someone. I strive for truth. So many atheists bash Christians and are incredibly hateful and angry. That seriously isn't necessary. I could honestly make a whole speech on science proving Christianity, but it would literally take pages and pages to write and I'm really only on these videos to brush up on my biology (I'm a Biology, Chemistry, and math tutor at my college and am pursuing an MD career). Seeing some of these arrogant atheists is just too much, and sadly, they wouldn't even listen even if what I have to say is right. I'm not going to go into too much, but seeing these comments from some of these fellows is out of hatefulness as well as ignorance.
No they don't go hand in hand. Christianity is fake, oh btw you realize that there are other religions in the world?
things in the bible and things science have proven at times directly conflict.
omg you're right.... it's almost like religion was created to explain things that we couldn't understand at all at the time... wow
+Katie Annabelle Cochran What angry atheists are you talking about?
Katie..... science is effort ostensibly trying to ''understand why people could possibly envision a voodoo version of creation''...namely some altruistic Hebrew patiently roaming the clouds who loves us but somehow creates misery via disease, discord, hate etc.
The hats really cleared things up for me.
your drawing skills are fine plus it good to lauph a little....your the best even my teacher uses your videos in class :) keep it up your helping a lot of poeple.
Creationists here are in the wrong class. You're supposed to be in Introduction to Mythology and Fairy Tales.
don leavell Boy, Biology is a required class for me to graduate. So therefore I am not in the wrong class. And even though I do not agree with evolution, that doesn't mean I cant learn about it.
Hannah Farley Girl: If you don't agree with evolution, then you're still in the wrong class in biology. Evolution is not a matter of "belief." There's more evidence for evolution than for gravity. You eat food that's been artificially selected, which we learned from "natural selection." Consider the fossil record. But while here, if you're a creationist, I invite you to take the Nobel Peace Prize today with your reproducible, demonstrable test results, which science is required to do. What's the hold-up? And science has wonderful predictive power because it works. Peace.
Just saying I would rather not take Biology. I hate that class. Science doesn't interest me all that much. But even though I do not enjoy it, I take the time to learn about evolution at times, it interests me to learn about what others believe to be true.
I do want to point out that I don't hate anybody or dislike anybody for believing in evolution, it's just not something that I find to be true and I hope that one day, as a Christian, that others will find out the truth for themselves.
Hannah Farley It's very revealing that you think science is based on belief. Wrong. Science is only reproducible, demonstrable test results and it's always peer-reviewed. But have a nice trip. I don't hate anybody as well. That's a straw man argument. Test results, only. No belief involved. That's reserved for and required to be a religious person.
don leavell You say you don't find evolution to be true. That reveals that you are unaware of the tenets of evolution. It's a fact, dear. Sorry to be the one. But you guys can't prove any of your miracle claims and disregard that which can be proven. That's a state of mind devoid of critical thinking. You want it to be true. That's the fact you should realize. Peace.
thank nobody I'm not religious because idgaf
I learned more from this than from one whole stencil and a lot of philosophy lessons
better drawing skills than me but very educational video! Thanks.
I swear that all youtube channels like crash course make the exact same example, which is peppered moths.
I am a Christ follower, however, I love science. Does it really matter how God made the universe? He is the Great I Am, He can make the world any way He wants. If He wanted to make it through a Big Bang then He can by all means create it through a Big Bang. In short, who cares? End of discussion.

How did your god come to be? Why is he a he? What is the evidence of such creature? If one thinks that god always was, then why is it unthinkable that an endless number of universes goes in and out of existence all the time like subatomic particles does. Saying that god exists is not a conclusion, it's lazy, it's saying "we don't know therefore we
will never know", people has said that about all sort of things and has over and over again been proven wrong as science proceeds. Why can't we just say the scientifically honest thing "I don't know yet, let's find out"
Evolution = Just a bunch of dudes
*and dudettes
Thank you so much!
This blew my mind, mostly cause I'm not that educated lol, but a DAMN good presentation nonetheless!
so let me try to understand what khan is saying here, this Speckled Moth did not change in any way whatsoever there were always dark Specked moths and light Speckled Moths, and one was hunted to near extinction due to changes in its environment, later the environment changed back and it favoured the other Moth. I see, so that this Moth started out as a Moth and stayed a Moth, and the bacteria he talks of well that changed from Bacteria to, well Bacteria.
Can I say just as a dumb blonde this has nothing to do with macroevolution whatsoever? This is simply saying if men prefer blondes then they marry blondes, the children they produce will have higher possibility of having blonde children, the brunets never marry because no one wants them. The children will be bigger, smaller, smarter, thicker, but will always be what they are Homo sapiens.
So there is no evidence here for macroevolution whatsoever is there, it’s just scientist telling us what we already know. Really I am a Christian and some of the comments on this thread are very offensive indeed, in fact just change the word Christian with black and many identify themselves as racists don’t they? now I don't mind a little name calling I have a few names of my own for my adversaries after all, but am I supposed to take those who pour scorn on me based on nothing more that if men prefer blondes or not, because that is what it comes down too. I can't believe people are so naïve not to check out the facts and other possibility’s before engaging in a religion, me I make no claims of openness or knowledge of science, if 100 scientist says something is fact and one doesn't I would be suspicious of the fact, I don't know any scientists who dispute gravity. The bible is right because God said so, I don't see this is any different than saying science is right about macro evolution because richard dawkins says so even if a thousand others agree with him, it only takes one or two to put into question his/their reasoning, Now don't get me wrong here, you can say you have "faith" in these men and that's fine by me, but don't claim to have a greater proof for what you claim because you are simply indicating to me that you think your religion is better than mine, and you only have insults and abuse to back up your claims and a good dose of faith too. Welcome to the world of faith and religion people.
Yeah... This was an INTRODUCTION to evolution. He was talking about natural selection in present time... You're right it didn't have anything to do with the evolving of a species... Because that wasn't the subject of the video. Evolution is a vast topic with an incredible amount of information and support. It took Darwin over 20 years to formulate his theory. I would encourage you to read his work, as well as a book called "Ever Since Darwin." Please don't formulate your opinion solely based on what you watched in a 17 minute video. That's just ignorant. I understand where you stand on being skeptical and not believing something without proof. But.... believing 100 scientists' viewpoint should be easier than believing in god the way a book written over 2000 years ago explains it. (not to mention the countless changes the bible has undertaken)
Noah Sawyer Hi Noah,
_Yeah... This was an INTRODUCTION to evolution. He was talking about natural selection in present time... You're right it didn't have anything to do with the evolving of a species... Because that wasn't the subject of the video._
Oh I see, only I was told on another thread that there is no difference between macro evolution and micro evolution.
Only it would be a little misleading to use the evidence of a moth changing colours, and building on this for a change in species. I would hope you agree with that.
_"Evolution is a vast topic with an incredible amount of information and support."_
Micro evolution does yes, macro borrows from micro because it doesn’t have any evidence outside imagination and hope, I have a list of scientist on my profile page who dispute the science behind macroevolution, can you give me a list of scientists, who disagree on gravity?
_"It took Darwin over 20 years to formulate his theory. I would encourage you to read his work, as well as a book called "Ever Since Darwin." Please don't formulate your opinion solely based on what you watched in a 17 minute video."_
No I have studied it at school my science teacher is unable to give any evidence, I challenge him on his assumption that macroevolution is a graphic based science, showing nothing more than an ape slowly raising in its walking position, I’m afraid unless that’s a 30 million year old polaroid then that only counts as imagination and not science. further a moth becoming a moth isn’t evidence of anything is it? No you have to explain the shear mathematical impossibility, just adding a longer time isn’t good science its just illusion. I’m afraid you have science real science working against you, and real scientist who are not so gullible as to be impressed by graphics, it gets worse for you, you now have scientist so desperate that they have to reinterpret nothing to mean a quantum vacuum, I mean how far will you go? maybe show me a moth that changes colour as evidence perhaps!
_" I understand where you stand on being skeptical and not believing something without proof. But.... believing 100 scientists' viewpoint should be easier than believing in god the way a book written over 2000 years ago explains it. (not to mention the countless changes the bible has undertaken)"_
Why have you brought God into this? Why have you mentioned the bible? Why do you try to justify macroevolution by trying to disprove some religion? Why not justify macroevolution on its facts? The simple truth is, it’s a tool that you use to disprove a religion, that is not only sad but it’s not the purpose of science. I think you have lost all credibility I’m afraid.
1. You have used an old book to justify your argument (Darwins) then condemned another old book because it didn’t suit your purposes.
2. You give credit to 20 years work and reject a 2000 years’ work, because it didn’t suit your purpose.
3. You tried to justify a fact in one field by disproving something in an unrelated field; I would have to ask why you would need to do this if you have a mountain of evidence to support your case.
4. you mention a god but do not give him his deity, you create him as a straw man solely to further you argument which as I have already said has nothing to do with God, but if it does then you have to give the correct status to that deity.
5. You need to give the evidence for the countless changes in the bible? Moreover, how this proves macro evolution.
I will await episode two of this video to see where it is going, I hope we don’t see any more of the moth, as I could have given a much better example of microevolution from a 2000 year old book called the bible.

***** Hello Dan,
Yes I completely agree, natural selection is that process exactly.
if you feel you have been worshiping an abstract entity then you have! I doubt you worshiped, do you mean you went to church perhaps?
Worship is a personal thing isn't it? if you and I attended my church and we sang a hymn, then I would be worshiping and you would be singing, I think you mean this perhaps.
I don't know what you mean by it works? it doesn't work for me? I mean what do you expect it to do?
I just live by the bible you live by whatever, so what, we both are living. When it rains the rain falls on me and you! I will die so will you; I may have a miserable life and you a good life.
When I die I will go where I want to go, so will you.
I was chosen by god for no reason whatsoever, so was your family, it sounds to me you wasn't, I am not one jot better than you, but I was chosen because it pleased god to do so, it pleased him not to choose you, I can no more become a non-believer than you could become a believer, it gets more bizarre, I have no more evidence than you do for my belief than you do for your disbelief! Odd isn't it, you would possibly have a brother who believes, yet you were brought up together.
I was in church one week and I met this broken lady, it made me cry what she told me, she lost her only child, and was unable to have more, and she told me this is why she had so much faith, my auntie, doesn't believe because she lost her husband in a car accident, when I read the bible love jumps off every page, when you read it . . . . well you tell me lol.
I like you, honest, direct, and respectful.
Nice to meet you dan.
Sarah
***** well I have to have my homework in by nine otherwise its a visit to the headmistress again, so I will be visiting her again, my dad won't let me wear makeup and all the other girls are allowed. I don't have a mum, so I am mum to my dad and brother, well in truth I am their slave. I love to babysit but my brother has to take me and pick me up otherwise my dad said I can't do it, if footballs on the tv he won't take me, footballs always on the television, and I hate it, on family days out guess what we do? we go and watch a football match, all in the name of family bonding of course, I note we never bond at the ballet. oh and the only decent boy in my class thinks I'm mother teresa. now if this wasn't bad enough, I have idiots asking me what's wrong!
Não existe uma divisão na evolução em macroevolução e microevolução, essa linha divisória serve apenas para fins didáticos. O fato é, que as micro "evoluções" acontecem o tempo todo, variando sua frequência de organismo para organismo. Basta que isso ocorro por centenas de milhões de anos, como de fato ocorreu, ou apenas algumas eras geológicas, para que seres com cérebros desenvolvidos como o nosso apontarem esse acúmulo de "microevoluções" como sendo uma macro evolução. Porém o conceito de espécie não é muito preciso, logo uma especiação (exemplo de macroevolução) poderia ser caracterizado por dois organismos intimamente relacionados, na história evolutiva, que não conseguem mais se reproduzir. A bem da verdade é que, para entender a evolução, é preciso primeiro, deixar o negacionismo de lado.
i made a playlist of your biology videos in order to study for my biology (12) exam!
thank you!!
how did you do
Please do a biochemistry series!
this helps me
