My Kids are Mutants

Seriously:

"Ten thousand years ago, no one on planet Earth had blue eyes," Hawks notes, because that gene—OCA2—had not yet developed. "We are different from people who lived only 400 generations ago in ways that are very obvious; that you can see with your eyes."

According to these guys, the pace of evolutionary change has accelerated over the last 10,000 years since the agricultural revolution. We're acquiring mutations (like blue eyes) faster than we did previously - a lot faster. Between 10 and 100 times faster.

I'm pretty excited to see if my grandkids have four legs. Sweet.
