I like that he included his dad into this.
Biology explains why xou shouldn't compare yourself to others, cuz we all are unique
You are unique, just like everyone else.
4:08 man, those turtle ducks from ATLA are very cute!
Did you just almost say/spell Atlan?? Like the name for Turtle Island
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.
Being randomly unique and being specially unique looks different tbh😅
Love how easy you explain. ❤
We're all uniquely stupid and that makes each and every one of us special. Remeber that. :)
Thank you!
I really like these and the topics are interesting too
I like your video, it's fun and educational all in one!
THANKS
Wish this was around when I was in high-school
Best gag yet.
great video
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 have a shiny Scyther XD
i passed my university first semster bio with a b, if i had seen this before then i would have gotten an A haha
🎉
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
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 just realized.... i'm just seed😢
Lol your dad did good 😅
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.😮😮😮
Nice video, but why does the video only refer to humans?
type awesome on you're keyboard
I’m first
I am first🎉. Good video. Good luck . 😊
