I had no idea there were this many examples of evolution caught in the act in a human time frame. I had heard of 3, the recent finch evolution in the Galapagos, the recent lizard evolution on Cypress, and the color change of butterflies (or was it moths) during the industrial revolution when tree bark blackened from coal soot.
Anyway, this is a great page full of examples, including new speciation and even whole new organs evolving. Cool stuff.
If anyone actually asks you “were you there?” The correct answer is “Yes. I was there.”
