The generation-to-generation natural selection of Galápagos finches is particularly fascinating—it shows evolution as a process that isn’t always slow, and anything but steady, but something very much alive.

Biologists aren’t reading “On the Origin of Species”? That’s a shame—it’s a really interesting, really enjoyable book.

It was just one of the populations that, around the 31,500th generation, suddenly developed the ability to metabolize citrate, thus doubling its available food …
