    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😅

    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.

    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.😮😮😮
