goosebumps are rly cool
| yeah, you're right. goosebumps are low-key quite interesting
| Similar story with the muscles that move our ears
Not exactly the same but I'm a big fan of the recurrent laryngeal nerve, especially in giraffes but the human one is interesting too
| >>1109325 the nerve going all the way down then turning around and going back up a giraffe neck isn't interesting to you? The human one has the same thing just on a shorter neck

| i went down a bit of a rabbit hole wondering what causes goosebumps and of course that led to like literal responses like the cold and excitement and stuff. but it all goes back to when we had more fur. if we did, goosebumps would essentially make us "flex" our fur and make it denser. we'd do this in conflict, in order to appear larger, or in times of cold, to stay warm.
other animals still do this, like cats and dogs, but its weird we do even now that we no longer have fur
