Evolution

I wonder if evolution cares if we all look different to each other? That is, is there an advantage to the species of each of us being unique to look at?

It’s possible that our differences are a by-product of other evolutionary requirements.

Or that natural selection is actually trying to homogenize us. Come back in a million years and we might all be sneetches.

Just possibly we are a species of train-spotters. To dogs we might already look like sneetches.
