Buttering me up? I hope it’s real butter. ;-)
Let’s say that it’s been believed that you finished off 100 servings of popcorn over the past 20,000 years (hence the grey whiskers). But it’s now believed that you finished off 2,000 servings of popcorn over the past 200,000 years. The rate of change of your popcorn consumption would thereby have increased by twice.
Substitute DNA changes for popcorn servings and you have it.
