Evolution is happening all around us. In many cases – lately, due to technological advances in molecular biology – scientists can now describe the evolutionary process in exquisite detail. We understand the genetics, development, and biomechanical processes that link changes in a Galapagos finches’ diet to the shape of their bill. And, in some cases, we can watch as one species splits to become two.
