Re: how to surive and prosper after Armageddon

>>And what about all the placental, marsupial, and multituberculate mammals
who were not insectivores?<<

Well, one might argue that all of them died out and then the insectavores
radiated back into the old niches, but I think that nothing behavioral is
going to solve this problem.

Fundamentaly, the only land animals that survived the extinction (most
extinctions, for that matter) were the small creatures.  Insects, crocodiles,
lizards, birds, turtles, worms, and mammals, etc. were all groups of animals
that held a large number of small species in them at the end of the
Cretaceous.  (non-avian) Dinosaurs and pterosaurs had no small members and so
died out.  Many small animals are insectavores (or insects themselves) and
many burrow so there are some links there, but it all boils down to this:
size does matter.
