There’s no doubt in my mind that evolution is a fact. There’s no other way to explain how I got cat whisker genes translocated into my ears. Every now and then I’ll notice an errant hair growing out of my ear that is so long and thick it brushes against the wall as I walk down the hall. It’s a throwback for most humans. One of those things like your appendix. Totally vestigial in most of us, but still useful to some in the south as a means of alerting them when they are about to stick their heads into a rabbit hole of insufficient diameter.
