TRANSLATIONS:
While we don't allow dubbing of our videos, we do gladly accept subtitle translations from our community.

If you have a concern about community contributed contributions, please contact us.
We like to pin clarifications or corrections on our videos. We appreciate comments that bring them to our attention. There is a text box in this video that states that natural selection acts on populations, but we want to clarify this. Natural selection is based on differential reproductive success of individuals and this is a mechanism for evolution, which acts on populations, in order for this to happen. Natural selection does *occur* in populations (some references will use the words "*act on*" such as this example esajournals.onlinelibrary.wiley.com/doi/full/10.1890/0012-9623-95.2.24), but as a mechanism, natural selection does so by differential reproductive success of individuals. Our focus is to prevent the misconception that it does *not* produce an evolutionary change within the individual. The individual's survival and reproductive fitness will affect the population. Since we can't easily edit the text box, we are going to opt to remove the portion with the text box as it is explained without the textbox later in the video.
Have you ever thought of talking with sft
I am a biology major but was losing my interest recently in school and my major. I came here through recommendations last night and watched almost all of your videos since. Each video reminded me why I chose biology in the first place and got me excited again. Your excited voice and sense of humor got my hearts beating with my hopes and dreams once more. I cannot thank you enough. How did I forget how much I loved biology? Thank you, thank you. XOXO
I feel you.
Jimin Bang army?
@Aydon Calvert Do you know why people associate love with heart? It's because ~loving can heart, loving can mend you soul, but is the only thing that I knowwww
how are things now?

As 34-year-old college sophomore, I learn more from these videos than I do reading the text provided by school.
If that's your actual photo you look great for 34!

same bro
same :D
lukeyjukey SAME
Everyone saying they're a teacher while im here trying to get an assignment done with this video 😅
You're not the only one lol
Same here
Saaaaame
I learn more from the Amoeba Sisters than my actual biology teacher... LIFESAVERS!
as always, succinctly and simply illustrated, fun to watch, and educational. thanks for making this.
We have a resource that goes with this video! Find it on www.amoebasisters.com/handouts
we just covered this in class last think, your video was amazing, a two hour lesson summed up in 7 mins
Speciation does not support evolutonism as it is an example of stasis and stasis is the exact opposite of evolution. For ex. over 200,000 species of beetles are all still beetles. There are thousands upon thousands of species of birds, bees, lizards, trees, bacteria, trees, yeast, flowers, whatever. If a new species develops with any of those groups at all, you can bet your bottom science dollar that it will still be just a beetle, bee, bacteria, tree, fish, or whatever.
We are supposed to fill in the blanks here with...faith...and think, "Well! If new species develops then things just keep evolving and evolving." But the next step above a species, in the Annimal or Plant Kingdom, is a Family. We aren't seeing any new Families forming. Anywhere. Ever. Accorrding to Darwin's so called Tree of Life and peer reviewed evolutionary literature, new Families have evolved. Over and over and over.
However, nature operates today as it did in the past. In the real world, with trillions of life forms, we never see anything developing above the level of a new species. The life forms out there have purportedly had eons and eons of ancestors preceding them which should be showing at least one example of a part this Family "transitioning" to be another Family.
But we only see that in the unverifiable, purely theoretical, realm of evolutionary literature, never in any life around us. If there is no evidence for transtiions from one Family to another - and please provide data if you know of any such evidence - then there is no evidence for evolution. But that's just for starters. If you want to take a walk on the wild side and look outside the box, you may find it interesting to see some of my other posts here.
My seventh grade life science students LOVE your videos. They always say "yay" with the utmost enthusiasm when I say we are watching an Amoeba Sisters video. Thanks so much for posting these. They are helpful, relevant, and loads of great fun.
Even as a college student these videos are excellent for reviewing materials from my lectures! Huge fan! Keep up the great work!
I'm a student who's trying to learn by myself and be Infront of the teacher since he's so fast,but what I can say is that you've really helped me ever since COVID came to existence.May the good Lord bless you
Who's here because your teacher is making you watch this during Corona Cation
me :)
bro I hate this online school, I honestly would rather be in school, im a sophomore
Yow just wanna ask are y'all Grade 11 or 5th year high school? I'm not sure if this is the correct lesson I should be advancing on

11
meeeee
I'm telling ya.. illustrations make a difference in learning. With your voice and the illustrations.. yall make a killer team! I am learning so much in such a short amount of time. Everything that I am learning in BIO right now is clearer now because of yalls videos! THANK YOU FOR HELPING US AND OUR CURIOSITY!!
best thing on this planet is your channel
This is very helpful for the things that I did not understand in class. Thanks for keeping everything so simple and easy to understand.
Hi. Keep up the great work you two! You help keep Biology interesting at times when I'm so tired I can't keep my eyes open lol. Hope your channel grows bigger. I'm sure it will. Just keep sharing that knowledge to the world! Love! Peace!
This is so convenient! Everything we cover in biology class, you guys cover at the same time. Great video, and I'm sorry you weren't able to watch CatDog. Great show
Thank you for creating these videos to enhance student understanding! Very helpful in my teaching of 7th graders. :)
My bio final on evolution and ecology is soon. Ya'll just saved my life 🙏🏾
Are tortoise and turtles an example of habitat isolation?
love how moo sorta hangs out in lots of the scenes of the video. thanks for helping me with science every day
These videos are so addicting.
Thank you so much. ❤️
I love your videos ever since my teacher introduced your channel to my class!
My dear sister
Really your teacher recommend you to watch these
Which country you belong to 🤔🤔🤔🤨🤨🤨
haha me 2
Such a great video!!! Definitely going to use it in my classes.
Bio test next period! Time to watch amoeba sisters
Loved it. What a great summation of speciation.
the best channel to watch biology videos... and also good for quarantine times.... 😒😒😒
This is the first of your videos I've seen.. Super creative visuals and great script for conveying this info in such a digestible manner! Keep it up :)
Thank you, amebo sisters! you're saving my bio grade
The default dance is truly a masterpiece. Never, in all of history, has such an artistic masterpiece ever been created. The choreography is possibly the most beautiful sight ever beheld by the human eye. The sharp sound of the SLAP when the player’s hands collide perfectly with the beat of the song sends a bone chilling shiver down my spine, every single time I hear it. I find my self watching my in-game avatar performing this phenomenal dance ritual for hours on end. The beat of the song is without a doubt the most amazing musical composition in history, one to rival, if not surpass the complexity and beauty of Mozart’s classics. The default dance has truly revolutionized the future of music, and how artists should aspire to create. Some would describe the default dance as a meme, or just part of the game it is appearing in, however I would strongly disagree. These people simply do not understand that the default dance is the center of existence. The universe, science, and evolution are purely myths, as the default dance was the first life form to roam the Earth. Everything; human beings, nature, everything that defines this planet, has originated from ‘the building blocks of life’, the default dance.
Yes but why here
ALWAYS THE BEST.KEEP UP THE GOOD WORK.MAY GOD BLESS BOTH OF U
Very nice video. I'm not in school, but as an artist I like to come up with fictional animals, though I want them to be as scientifically accurate as possible (at least up to what is known currently). I really appreciate these videos. It's hard finding such specifics put into a video format. Keep up the good work. ^ - ^
this channel helps so much with studying, keep up the great work
Thanks for this video. I also understand that "fusion...ha!" reference!
Started loving biology after seeing these videos. Thankyou so much for your efforts 😍😍
We really love to watch your videos, fellow Amoebae!
wonderful explication, I´m from Brazil and i´ve learned so much more w this english illustration than in portuguese classes
These videos are so good ! It's a fun way to learn
Bring back this intro!!! Love it guys ❤️
this page is my life saver
your videos are the best (for learning)i have watched by far...everything about this video is just great😍
I absolutely loved it Amoeba Sisters forever : )
Such a great presentation.
Ameoba sisters ON TOP ONCE AGAIN 👑👑👑👑
I find it surprising that the Amoeba Sisters will create a video about the same topic that I am currently learning in class... within the same week. I think the same thing happened in the Natural Selection video. It really helps to reinforce the material. Thanks for making these videos! Keep up with the coincidental uploads!
Awesome, I'm very impulsive so your interesting videos really helps me understand. Thanks sistas
Its such a unique way of teaching really impressed great job loved ur video
♥♥♥YOUR VIDEOS ARE JUST AMAZING, PERFECTLY EXECUTED♥♥♥
I just love watching your videos, the animations, cartoons, way of teaching, script are just amazing. well done Amoeba Sisters. your channel is great. keep up the excellent work.
HUGE LOVE TO AMOEBA SISTERS FROM *INDIA*
Another interesting video I’ve watched. I’ve had to watch so many interesting videos for my class. I’m enjoying these kind of videos so much. 😁
Loved the video and always staying curious 😎
Thank you guys sooo much for these videos :) Can you possibly d one about plant transport? Thanks!
Lovely videos. Keep them coming !
This is such a cute informative video. Loved it!
This video is great... Helped me a lot
Love your videos,
So?
amoeba sisters really helped me with my studies involving biology, it never failed my expectation, I learned a lot from all of your videos. I wish all of the topic that is hard for me to understand is here and I can binge watch them, I can't explain how grateful I am that you have all this full of information videos, hoping that you will continue upload videos to help a lot of students struggling with their studies.
Thank u so much excellent explanation
My teacher told me about you and now I love your videos
Love your videos, you are just amazing! ❤
I regret i didn't find this channel so early 😢amazing !
thank you amazing explaination
this is really helpful for my science assignment on edgenuity
Great explanation
Going back to in person school this week!
This is so helpful. A DogCat would be nice.
Thank you
I loved that show
I love you guys!!!
Thank you so much for this! I'm a 10th grade CBSE student and this is gonna help me so much in BOARD EXAM
Really there is no topic
Great video 👍
thank you
I can say you are saving my life If I did not see this video I would be fail :)
This is the best channel
You guys rock!
You guys need more subscribers
That's pretty good!! 😀😍
I saw a docu series recently and in one episode they talked about a Tigon (Tiger Lion Hybrid) and how Lions usually have a gene which causes them to grow abnormally large physically ( found in the father's karyotype) but the mothers have a gene that prevents this.But when a Tigon is born its Abnormally large from a lion and a tiger due to the overgrowth gene, which doesn't allow it to live long. I think its the best example of the 2nd Postzygotic barrier you guys mentioned
I think evolution is fact love from India🇮🇳
Wow thank you♥
i love the intro music...
Thankyou, I got Taxanomy's paper tomorrow.
I love you amoeba sisters
Great vid
0:20 Dragon Ball Z reference, I can only think of that now.

Simple and attractive illustration, exciting voice, made me feel the topic. so coool🤗
i love your channel
I love biology
THANKS TO U!!
it is really beautifully explained. tq very much. but mam i have one doubt that is, what will the phenomenon be called, when one vegetation completely takeover other vegetation. example: pine trees taken over by quercus species
Loved this video!
thanks for the vids I love science
You have a pretty voice
Awwww, thank you so much :D
And i learned alot from you video thank you so much, are you a professor?
I'm sure that was you, Pinky.
The one video that clearly explained sympatric speciation 😭
