    This video is criminally under-viewed. This speaker has everything: the wit, the brevity and the dedication to wear that vest!

    My personal theory is that in the case of vertebrates we all descended from an ancestor that could change it's skin like octopus do to trick predators.
    As early vertebrates became bigger, faster, stronger they became the predators and most lost this ability. But the patterns were kept in our DNA. It would be like having a storage to choose from randomly. From there as generations pass by the patterns mutate on their own slowly but noticeable.
    In the case of birds and mammals. Eumelanin starts as spots, t shaped, c shaped, lines, etc. As the fetus grows, so do the patterns. When they touch each other they become more complex.
    This would be like Dark Matter and the Universe. Dark Matter is the glue of Mass.

    I think it’s difficult stuff. When you have a agar plate with bacteria I can understand the system. But how do the body cells communicate in animal to make such patterns. Is there an inhibitor or activator body cells talking to each other?(excuse me for my bad English, I am Dutch)

    Can this be applied to Pandas colors?

    You can't talk about equations and then not show us any! I feel denied. :(

    I feel like there are so many parts where he was trying to be funny but no one laughs so its just awkward.

    you didn't explain the chemical nature of the patterns at all. the sensitibity to initial conditions is also not mentioned. How dumbed down do you have to make these exactly? because that's not really complicated ideas to explain here. I bet there's lots of weird stuff that happens in between for that lol

    Not really accurate to say Alan Turing shortened WW2 by two years. The Manhattan project ensured WW2 ended in 1945 and would not have gone on any longer

      We don't know, I'm surprised as you are.

      No pattern emerged yet. Let's wait for diffusion

      ​@@significantmatters8740i sense some instability in the pattern.
