Re: Earth's wobble killed off mammal species

Is species longevity really an objective metric in this instance? What
kind of species concept?

No those figures are of the right order. Mammalian species longevity was on
the order of 0.3-1.2 million years during the Pleistocene and 3 - 6 million
years in the Neogene (there is a great deal of varition between orders).
Bird species were more long-lived in the Pleistocene, about 6 million
years, but in this case there seems to be little difference between the
Paleogene/Neogene and the Pleistocene.
