Fulica americana, the American coot, in front of a prominent Las Vegas casino and hotel. I'm remiss to say that I had to travel all the way to Nevada to see my first coot in the "wild". |
If you're still one of those people that doesn't accept that birds like the one above are in dinosaurs, perhaps you should have attended the talk by Jack Horner last night (which Brian Switek of Laelaps dissects over at Dinosaur Tracking). He spoke about dinosaurs and the proofs of evolution, and while the talk was, as per his admission, meant for a more generalized public (as opposed to a room full of paleontologists), he still brought home some very important points. Whether or not any paleontologist in the room is going to agree with one another on certain aspects of the science of paleontology (species designation, anagenesis v. cladogenesis, etc.), there is one thing that (most) do agree on: evolution.
There is no argument over the idea that generation after generation, traits accumulate in a lineage of organisms, that over time, result in the "birth" of new organisms. And we can see this idea proven in a number of ways. Selective breeding of domesticated animals results in these very changes, over relatively short spans of time. The presence of vestigial body parts shows that, at one point, an organisms ancestors must have had those body parts, and they were reduced over time with each generation. The rock record shows a real succession of living beings over massive spans of time. Modern genetics allows us to learn things that the rock record never could. We can now tell, with little doubt, how closely related living organisms are by looking at their genomes. And maybe one day, we'll be able to do the same thing with extinct animals. So like it or not, the evidence for evolution is there. And as Horner put it, if you can prove otherwise, you'll easily become the most famous person in the world, ever. Good luck with that.
Stay tuned for more from SVP all week. I managed to find the free Wi-Fi. Huzzah!
