Climate changes profoundly influenced the rise and fall of six distinct, successive waves of mammal species diversity in North America over the last 65 million years, shows a novel statistical analysis led by Brown University evolutionary biologists. Warming and cooling periods, in two cases confounded by species migrations, marked the transition from one dominant grouping to the next.I am quite sure that there is more to the Brown study than meets the eye since this information simply reflects what we already knew about how natural selection works in the wild. The story does, in fact, provide detailed information about mammal extinctions and radiations. It is the way in which Science Daily words the headline that is amusing.
This “lack of randomness” was the crux of a piece that I wrote for CFSI a bit back. If anti-evolutionists or ID supporters are willing to argue that evolution is a “godless, random process” then they have to be willing to argue that climate change on the planet is also a random, godless process, since that is what drives biotic change. I haven't heard any of them say that yet.
