A survey of scientific responses to extinction at the present moment is fairly unambiguous, however. Paleontologist James Kirchner calculated in 2002 that extinction rates could more or less be statistically inferred from the fossil record, and uses this to quantify what he terms "evolutionary speed limits," which is to say the rate at which the Darwinian process of natural selection (which depends upon the effective extinction of species insofar as

These are large but slender mammals, with females usually exceeding males in size and weight.
