Did you just almost say/spell Atlan?? Like the name for Turtle Island
Biology explains why xou shouldn't compare yourself to others, cuz we all are unique
You are unique, just like everyone else.
I thought "Haha the spermary"... literally 1 second before He said it. God I love this series.
Man, I just love this guy's presentation style. Dj gametes is the wildest metaphor I've seen in a biology lesson so far. Keep this man at all cost.
It’s not just the combination of genes that determines how an organism develops, but also the expression of those genes as affected by external environmental factors which creates an innumerable amout of additional possibilities.
Love how easy you explain. ❤
Wish this was around when I was in high-school
Being randomly unique and being specially unique looks different tbh😅
We're all uniquely stupid and that makes each and every one of us special. Remeber that. :)
I like your video, it's fun and educational all in one!
I really like these and the topics are interesting too
Thank you!
Best gag yet.
great video
THANKS
I believe i heard 7:40 in crash course thrice already. It seems like i saw versions of this episode twice before the two earlier ones had a different host.
too good
cuz it's awesome:)
i passed my university first semster bio with a b, if i had seen this before then i would have gotten an A haha
As a twin I've wondered what makes us diffrent other than fingerprints bc our DNA is the same so cool
Pretty sure turtle ducks are an ATLA reference lol
I have a shiny Scyther XD
One in sixty four - uh - give or take a few orders of magnitude, heh Still I'm glad that I lucked out and got my dad's charm :D
Lol your dad did good 😅
I just realized.... i'm just seed😢
🎉
Nice video, but why does the video only refer to humans?
As I watch this I think of cats and dogs. They can have a litter, same parents whereas maybe two in the litter look similar. They can even breed with several partners and none of them look alike.😮😮😮
I’m first
I am first🎉. Good video. Good luck . 😊
