Red, Of Course!

One thing that has always baffled me is nails, as in toe- and fingernails. When I search for a reason why we have them, the answer always comes up to be the same: to scratch. Just think: Evolution spent millions of years to give us something to scratch with. Yet, there’s something slightly frivolous and laughable about scratching, almost like burping.

I wonder if we will have them in a million years from now. Today, we humans do not seem to spend a lot of time scratching, so what’s the need of keeping 20 nails per person (well, in most cases 20)? Now that most of us are lice free (most of the time) and rarely get exposed to poison oak, you just have to ask the question: Why keep them? Perhaps the reason is simply that we need something to paint red, like a firetruck.
