  • I wish I could find the sources from when I was reading about this months ago, it was more about evolution in terms of things that can happen and not ‘random’ mutations, and one of the examples was tigers with orange fur instead of green. It’s not physically impossible to have structural coloring (although the fact there are no green mammals suggests a strong inhibition somewhere along the line), but you first have to have the genetic and molecular groundwork laid to allow it to happen. Ex: it’s not physically impossible for animals to manufacture their own vitamin C, but humans just can’t do it because we don’t have the necessary molecular pathways other animals use. I hope that makes sense for what I’m trying to get at.



  • From what I understand green eyes are a bit weird as far as coloration goes, as they look green due to the way light is interacting with small amounts of melanin in the iris (the same pigment that makes eyes brown) rather than due to green pigment. I’m not sure that could be replicated in fur vs in a liquid environment like with the eye.

    Birds mimic green colored pigments with iridescence (except turacos, they have green pigments for real) in their feathers, but I’m not sure that’s something mammals can do structurally in fur the way birds can in feathers.

    I saw a guy doing this recently (not to a barista, but someone that worked with the public) and the only thing that kept me from losing my mind on him was knowing there was no way the worker wanted to deal with him AND me blowing up at him. He eventually just left, but it was maddening to witness.

    Also, IME upper middle and upper class people are about 1000% more likely to do this than anyone else. This douche sounded like the frattiest frat bro to ever frat.
