I would have bet against that.
Much of what I've been reading lately involves the idea that major evolutionary change can happen in big jumps very quickly. Stuff that used to be pretty difficult to explain with tiny change over long periods of time, such as the evoution of whole new structures, or the movement of the flatfish eye, can be pretty easily explained by changes in the time and place of gene expression in a developing embryo. In fact, embryologists and geneticists have done some pretty amazing stuff demonstrating just this idea. So, it's pretty cool that it can also work slow and steady.
In other words, evolution can find more than one way to skin a cat. Awesome.
Thanks for the link!
