Yesterday our department hosted
Peter and Rosemary Grant, who spoke about their 30+ years studying natural selection and finches in the Galapagos. (If you're interested in the book version of their work, check out Jonathan Weiner's Pulitzer Prize-winning
The Beak of the Finch.)
While the Grants give a great presentation, full of pictures the Galapagos finches in action, my first impression was that none of this was really groundbreaking. As the Grants mentioned multiple times in the talk, Darwin anticipated so much of what they observe in the Galapagos. In an age of molecular genetics, a long-term, non-molecular field study is bound to seem a little old fashioned, although the Grants have recently been taking DNA samples and incorporating the tools of molecular genetics into their work.
In the end, I came away from the talk satisfied. This work may not be conceptually groundbreaking, but I find it important for at least one reason: this is evolution in detail, in the wild.
