So the fossil record, I think, shows a fairly dynamic pattern: that following the Cretaceous extinction event, the K-T extinction event, there’s a little lag time for a million or two years, but then we get a tremendous radiation of forms, and those forms become more specialized, they get bigger, so that within about a period of 10 million years, most of the modern groups of mammals have em
