Me: Man, I'm taking Biology this year, that's going to be so boring.
After watching a few of your videos: Dang, I want to learn more!
Dude, I totally felt the same way.
Thanks Connor. My greatest goal is to never have anyone like science less as a result of watching my videos, and if they make you like it more, all the better.
@@2MC you are my greatest inspiration. I wake up everyday to see you upload, and I live my life hoping that one day, fate will bring our souls together. Thank you for everything you have done. #nohomo

@@avykomakula7295 yeah lol
Why couldn't my Bio professor have just shown this 2-minute video instead of a four-hour lecture? I understood more watching this video.
Maybe he/she still could, or at least share it with future students.
xdddd
In addition, Homologous Structures are examples of Divergent Evolution and Analogous Structures are examples of Convergent Evolution.
dude you are awesome. Why can't things be taught in class this straight forward!
Thanks Victoria! People like to complicate education, but it really is straight forward.
Glazing is crazy
Thank you!!!! My Biology teacher went to fast and was really bad at explaining. Thank you for preparing me for my Biology final!!
You're welcome Tommy. Good luck on your final!
Wait what grade...
I’m in Biology this year and I’ve got a unit test tomorrow… I think you just SAVED MY GRADE thank you so much 😭
Quick, simple, efficient!! Definitely coming back for your videos!
This guy makes 10x more sense than my professor and does it 10x faster
Maybe going faster just makes more sense
20 times faster in double speed
I really appreciate the concept of your channel. Its nice to be able to review topics like this one with a short video rather than sifting through a long lecture. Also this seems very well done for how new your channel is.
keep it up :)
Thanks, I'm pretty proud of my channel and have high hopes for it's future. Nice Overwatch vids BTW.
These videos are fantastic for my biological anthropology class. The two minutes is the amount of time to display the concept while keeping my students interested. Thank you!
I read an article and understood, but this had something extra. EXAMPLES! Thanks so much!
Him: and a fin of a shark
**draws marlin**
😅 Right you are.
i looked into the comments to see if it was just me that was disturbed by it XD
No no it was a goblin shark!
I understand this more. Thank you for this, this is very helpful!
This help me a lot, thank you 👍.
You're awesome!
Such a great and simple explanation !
Thankyou!! Your videos animations, teaching, everything is awesome!!!
Short, sweet and to the point. Good video :)
That is the goal every time, I'm glad you enjoyed it!
From now on I will never forget the difference between them.....thanks...this video really helped me...
I'm glad I could help, thanks for watching.
meyon kills yo
Very informative! I love this!
So helpful, thank you!
Thank you sooo much!! you're a life saver!!
Phenomenal explanation!😊
great video 10/10, thanks
I'm using your entire page for my AP bio final, thanks in advance.
Why can't my teachers be this easy to userstand?
They can, just too much politics getting in the way I guess.
Thanks 2 Minute Classroom, in a lot of cases that is absolutely correct. In fact, I left public school teaching for the very reason that so much of what we were made to do was not only unhelpful to students but often downright counterproductive. I hope they fix the system, but I fear it won't be any time soon.
Wow. I learned more here than an hour of class. Thanks so much!
❤️❤️❤️
I learned a lot thank you man this is so useful keep it up!🔥👌
You are welcome! And I plan to continue making videos.
thx because of u i am able to understand many important topic in just two minutes
Well, that was my intention :)
2020-2021 online people learning wya? Also good vid 👍
very clear and simple ,thank you
Glad it was helpful!
Thanks you so much!
Shark, AKA Swordfish;) Haha good video!
how do you deduce what a similar and differing structure is?
clear and concise tnx
thanks mate great work keep it up
You're welcome.
Bruh u helped me alot.
Thanks Don! It's really easy to remember once you realize analogous just means "coming from" and bats were once just rats with wings who couldn't figure out how to fly yet. Keep 'em coming!
Glad I could help.
:) I’m so happy i found this cause my teacher made it complicated
I'm glad you found it too!
This is helpful.
Your videos are very helpful.
Thanks.
best video sir thanks
really like this type of structure, all the drawings, side by side comparison, spoke very clearly. keep it up
Thanks Robin, I'm glad you enjoyed it and found it easy to understand.
Thank you 😊
what are the different types of homologies? general, special, and unique ? this is something i am personally having difficulty grasping
this video saved me, I have a Science biology exam tomorrow, thank you soooo much
I hope it went well!
thanks it did i got an A
This is nice
I loved all ur video, plzz add a video of theories of evolution
Thanks Kumar. I'll see about getting a theory of evolution video out.
thank you!!!!
You're welcome.
Thanks
Thank You!
You're welcome!
Great video! You made this incredibly easy to understand! Just a quick question:
Would the chitin that is present in the cell wall of fungi be analogous to the chitin present in the exoskeleton of some animals then?
Thanks. And yes, the chitin in fungi has the same structure as chitin in the exoskeleton.
Nicely made
Thanksss
amazing ... just "AMAZING"
You are too kind my friend, thank you.
I have a science final in a few days and this is really useful. Thanks so much!
You are welcome. Good luck on your final!
Thanks to you, I got a 94 today!
Awsm sir
It help me a lot
Thanx.
No problem friend.
Glazing is crazy
Interesting 🥰
Thank You
You're Welcome
thanks this really helped
Glad I could be of service.
:)
Lovin my mans voice
❤️
Question :Do analogous structures have same basic genetic program?
thank u sir
You're welcome!
damn your good my teacher listed you as part of the assignment
great video thanks!
Glad you liked it!
@@2MC i love your videos so much
please mention me my name is marie
GOAT lecture.

2 Minute Classroom thank you so much 😍
2 Minute Classroom Homology and analogy came in midterm yesterday and i answer as you said exactly , thanks a lot❤
That is excellent! I'm glad I could help.
take this sub!
😍😍😍
Hi! We have this paper that we're writing and we're comparing the internal organs of humans and rats. I don't know if I need to look for more sources but in my general understanding, both animals have a common ancestor. Are their internal organs automatically homologous because they have a common ancestor? Or do we have to compare each one? Do homologous and analogous structures work with internal organs? Thank you in advance.
Homologous and analogous structures could be internal. However, in the case of humans and rates, their internal organs very similar with only slight differences. Homologous structures have a similar structure and common ancestor, but have differing functions. The internal organs of rats and humans have the same functions. Heart pumps blood, stomach digests, lungs facilitate oxygen transport, etc.
Rats and humans are both mammals, so they share some mammalian common ancestor that likely had many of the same or similar organs that functioned in similar ways.
Have you considered becoming a book illustrator. Those drawings 😍😍
I would definitely consider it if those were my drawings, but I use animated whiteboard software, so it's all digital.
How would we tell if they had common ancestor or not if a pair of animals are given
Thank you sir. One question though, homologous features are evidence of common ancestry - but in order to know if features are homologous or not, we must first know if they came from a common ancestor. Am I missing something here or does that not make sense? It seems almost like circular logic.
Two features having similar structure is somewhat of a hint towards homology, but that must then be proven somehow, usually through genetic research. Think of a penguin flipper and a shark fin, both look pretty similar, and do the same job, so one might think they are homologous. But when we look at their genetic history we see that penguin flippers and shark fins didn't come from a common ancestor, so they are not homologous, but analogous.
I’m confused. Am I correct that both butterflies and hominids derive our characteristic basic structure from HOX genes? Does that mean both species are homologous?
Why are testis and ovary homologous structures,they should be analogous as they have same function of producing gametes?
Can you do more of evolution chap?? Please 😺
Any specific concepts?
if you may allow me to give you some feedback on your video to make it more addictive to watch. quick summary; faster rythm on phrases and words with less pauses between them, louder voice sound, has to be way above the background music. make it faster in tempo and your channel will get far. curious to see more, i'm subscribed. ps: your anonymous everyday linguistic teacher.
Thank you! I am always open to feedback. I have been hesitant to speed up because I have had complaints that it's already to fast. I have some ideas I can try though. I also agree with the voice vs background music comment, I need to find the right balance there.
Can i ask what's their similarity?
What can we say wing of a bird and wing of a bat.??
Both have same structure and function??
What about the smililarity of the both of them?
My teacher defined it differently homologous = same origin but different function & structure. Analogous different origin but same structure & function.
I would check with your teacher on this. We are looking at similarities in both cases, the name just depends on the origin.
How to identify whether it is homo or ana? Can you give some trick or example please
Anyone else year 9/form 3?
What do you mean by: “same ancestor?”
We come from monkeys so they must come from a certain type of species as well. For exemple birds and insects both have wings but they don't come from the same species I think.
I am not sure because it doesnt make sense that a monkey and a narwhal have common ancestors but a penguin and a shark do not. More confusing than anything but everyone in the comments are like "wow, it makes total sense ". I wish someone would explain further
All that "similar function, differing function,and similar structure, differing structure" stuff confused me. Ill just stick with the common ancestor explanation.
💯
Well
Yes
Can you tell me why this is analogous?
I don't think I'm understanding the question correctly.
The majority of organisms in the plant, animal, and fungi kingdoms are multicellular. Based on the last common ancestor shared by all 3 of these groups, multicellularity would be considered which of type of characteristic?
This would be homologous, because it has a similar origin.
dang it I'm so confused! I put homologous and my professor said it was analogous. I thought I understood homologous and analogous wrong. Thanks for taking the time to answer though!
@@ADultingisHarD91011 After reading the question over a few times, I can see that it is analogous, but also a very poorly written question.
It's analogous because the last common ancestor of all three groups was not multicellular, but unicellular. The question alludes to this by saying "the majority of..." but not all, because there all single-cell fungi for example. Therefore, multicellularity would be a similar function.
This question is poorly written because 1-the wording leads you to believe that the common ancestor was multicellular, and 2-It assumes you know whether the common ancestor was multicellular or single-celled, which you may or may not have discussed in class.
Hopefully that helps.
@@2MC Thank you so much!! that was extremely helpful
did the common ancestor of humans and octopus had eyes? if not, that means that our eyes are analogous
Covergent and divergent evolution
is the skull an analogous structure?
It depends on which species your comparing and what you are defining as "skull" For example, the skulls of all mammals come from a common ancestor, and are therefore homologous.
all these people taking biology and I’m just taking advanced 7th grade science😳
Woah, you're getting some serious education in 7th grade science, keep up the great work.
kaelin bar IM IN NORMAL 6TH GRADE SCIENCE
kaelin bar I’m in grade 11 biology LMAO
i'm practicing my english while i learn biology
i'm brazilian :D
Why you no color all aminals
I'm somewhat limited by the animation software I use 😕
him: *draws a swordfish* Yeah this a shark
its a narwhal
💖
That looks like a Swordfish 1:28
hai
The wing of a penguin and the fin of a bird are the same structure and therefore are homologous, not analogous
They are not the same structure, the bone structure and evolution history are different, but they serve a similar function. Therefore, analogous.
anybody elses teacher assigned this to them?
Smart teachers
1:53 is not 2 minutes
You're welcome.
That's a swordfish not a shark.
