I once saw a study that claimed humans were driving lizard evolution in Brazil. You see, the construction of a new dam formed islands, isolating a population of lizards from the mainland. Within just fifteen years, these lizards had bigger heads and mouths to eat the larger insects on the islands.

But is this evolution? Well, the lizards remained lizards, and none of them gained any new genetic information. All that happened was the lizards adapted to their environment, using the genetic information they already had. This isn’t evolution in action! It’s just adaptation and natural selection.

Yes, it’s lizards producing lizards.
