Eli5 : why do humans look different but animals and other species look the same?
In: Earth Science
In addition to the points others have made (humans have a lot of diversity from spreading all around the world, you can distinguish animals with practice but the method may be counter intuitive to a human), I’ll add this:
We are social creatures. It’s one of our most important survival skills. So have a ton of extra features to communicate with other humans (blushing, eyebrows, visible whites in our eyes, etc.) And a diversity of appearance to make us easily identifiable is an adaptive trait. Plus, a huge amount of our brain is dedicated to interpreting other people – their behavior, assistance, etc. – so we are hard wired to be good at it.
