do you guys do only genetics
You liked your own comment😂
oh boy natural selection
Pretty good explanation with simple and humble animation 😍
@@rohitisukapalli4499 No they don't
so you're telling me...it could really be this easy, but my professors just choose to make it hard?
Exactly! This was ALL.
@@swayampurnaa a living nightmare comrade.
Aooi
YuP
Literally :')
Today was my last day of school, yet I still find myself watching these videos.
Probably one of the best compliments we could ask for! Thanks for watching, and we hope you're enjoying your summer! ^__^
Jaiman K OMG SAME
These videos help me so much in class because my teacher sounds dumb
Ur a nerd
Summer coming in just a few weeks, less than a month, and we're not even studying anything like this in biology, yet here we are. These videos are awesome
You are just great, I go to University and tomorrow is my genetics exam. Since my brain is oversaturated and coffee doesn't help anymore, I just started watching your videos in order to relax. and I even think, they might help a little tomorrow.
How did it go
How did it go
How did it go
how did it go
how did it go?
Side note, at 3:38, when the question is asked which population size could be more affected by genetic drift, this is a wonderful analogy to how grades fluctuate more wildly early in the semester with few assignments (i.e., "small population"), but later in the semester, when there are far more assignments entered, the grade is much more stable, less likely to be impacted by any one assignment (i.e., "large population"). It helps reduce the number of students rushing to me at the end of the semester asking for some epic grade improvement. :-)
This helped me understand it thanks lol
I legit thought the answer would be the same thinking from a percentage perspective
waah, i got it
The "Notice me, Senpai" at the end omg ha. That's great
Aline Teran Lazaro yes they put naruto and dragon ball references too lol
ITS LIKE THE GUMMY BEAR WANTS PINKY TO NOTICE IT. OR THE OTHER WAY AROND
Reminding you of this comment you made 6 years later
For Halloween my biology teacher and another science teacher dressed up as the Amoeba Sisters.
THIS VIDEO WAS FANTASTIC! THANK YOU!
When you commented on this video you didn't have a youtube channel and now 450k+ 😃
We need more channels like these! Many times us college students get oversaturated with all the material, so having these to rewind and reinforce is really helpful.
best channel for science espically AP biology
NOBEL DJ you learn this in ap biology? I’m in middle school. Well I just graduated. Does that mean I’m prepared for highschool?
@@jaycema1012 in some ways it will be much easier than you think. but in many other ways it will be absolutely awful and nothing but patience and focus can prepare you
thats why i chose that over ap chem
sci show is way better
We learn this in A level.
Hey amoeba sis, do u even know?, That Ur videos helps me in getting concepts- simplified and easily memorable , for my medical college entrance exam (NEET) in India, yeah I agree that there is a lot more than the information in ur videos
But the core concepts becomes crystal clear like in this video, thanks a lot, and we remind u to stay awesome😜
Did you qualify ??
This style is so unique to other science videos. I love it, it was so easy to learn. Thank you!!
Y’all are magic. I learn a concept in science, it makes no sense, I watch an Amoeba Sisters video, and I suddenly understand it
I am pushing 60 and find myself teaching high school biology at summer school. last time I took a bio class in the mid 70s...these videos are great! thank you.....
@3.16 "I am groot?" *cute puppy face with big eyes, tilting head adorably to one side*
Puppies faces are adorable
Finished Biology finally and thankfully I passed and passed my final ! (Surprisingly)
I thank you Amoeba Sisters for helping me through that journey. With out you all I may not have passed and may be in summer school lol.
Thankfully I am not, but without these videos I do not know where I would be.
A huge thanks ❤️
you did a good job of explaining genetic drift in 4.5 minutes than all my biology teachers ever did in my whole life
Hey :) thanks a lot for providing us with these great videos ! I'm a college student from Belgium, and I still find them very helpful, plus they're a pleasure to watch ! Keep up the good work, you're making a difference for all us who sometimes struggle with biology :)
Yay! I got the notification right away! Good job amoeba sisters!
This was the best. Get it now after reading the definitions online 100s of times. :)
Having biology paper tomorrow. Glad I found this video. Love your voice!
1:04 "This just coming in, a group of young children start up the violent Scooter Squad, murdering thousands of insects under the wheels. With more on that our field reporter, Bryson Potts. "
"Hi yes, this is Bryson Potts. Today I'm nearby a recent crime scene, scooter tracks and dead insects covering the scene. Back to you in the studio Phil."
"Ok, coming up next, the new music ideo for Go Stupid is out now."
Lol
M a master's student ... And m very astronished to know u are doing a great job ... Thankyou 😍😍😍❤️❤️❤️
Thank you for explaining in very easy way... keep uploading new videos...

I wished they showed these videos after lecture in college it would literally tie everything together for the visual learners😩😩
These videos are AMAZING
High school teacher here. Love this for my introductory Biology class! Great job on the graphics ladies :)

you guys have helped me so much with my exams. Amoeba sisters 4 life🙏🙏
You guys make it look and sound so effortless. Great job as always.
Amoeba sisters cool video!
I'm a seventh grader and when my science teacher showed one of your
videos to our class today, i fell in love with this channel immediately!
I am now a fan and I subscribed! :)
Thank you so much! We're so glad you found us! ^___^
Amoeba Sisters no problem! :)
Max888 I found your channel accidentally
Great video. I used to teach an evolutionary biology lab course, and had this video existed back then, I would have probably recommended it for some of my students who struggled with drift.
Watching this before my biology practice exam tomorrow!!
U r supertalented....!!👍👍👍 thank you...
Im a senior in high school taking AP Biology and these cute videos help me sooo much!! thank you !
this channel is a gift from god
Great job guys..🤗
You guys are actually really helpful with science, thankyou!
Очень крутые иллюстрации! большая благодарность авторам, очень помогаете 😍
awesome explanation
The one day before study-Amoeba Sisters about to come in clutch
You made it awesome ,.......Thanks...
This is so helpful, I'm using these videos to review for the AP Bio exam coming up. Even though the content is not as thorough as the stuff I need to know for AP Bio, it's such a good review to help jog my memory again from the jam-packed AP content. 10/10 recommended for AP Bio kids (and everyone).
mines too i’m so scared lol
Amazing explanation
My bio test is tomorrow and I am non-stop watching your video, I did a list that I have to know and you have all the videos, you’re such a life saver!!
Please make video on what is Gene Pool and why it is important to preserve it.. please please please....
Like Seriously You made it sooo easyyyy 🙌🏻❤️
This is why i choose this channel to learn science
So cool!
Thank you guys soooooo much for making these videos!! They're SO HELPFUL
I'm an adult who just wanted a refresher studying for the MCAT, but this was so easy to understand and yet entertaining enough to follow for all ages!
How did it go with the MCAT?
Haha, 506 first try and am currently in a US medical school! @@sandrasorto8375
I always love watching these videos because they are so informative. I always find myself watching these everyday!
This is helpful, thank you so much for thisT^T it makes it easier for me to understand. I have a formative exam next week on Tuesday, I can't wait to smash this out💜

*Watches every biology episode of the Amoeba Sisters*
These videos are the best thing that ever happened to my bio grade.
ohh my duck. This is soooo good. thank you so much :D
great vid thank you
TYSM! Test tomorrow!!! Ekkkk
Soo easyyyyy to understand
Thank you!
Thank you so much for this, I could not understand genetic drift for the life of me and this explained it perfectly.
U r really ossm .........u teach in interesting manner srsly 💖💖💖💖💖💖💖💖💖💖💖
These videos are awesome they help a lot with my college level BIOL class plus it makes the curriculum really fun!!
This is the cutest way to learn ecology.
Loved it, simple and straightforward. The examples were perfect. Thanks :)
Thank you guys soo much! This is soo simple! I don't know why I was struggling with this. I'm going to draw the amoeba sisters and frame it in my bedroom.
