Re: Carcharocles [Carcharodon] megalodon
I find it very strange that Lipowski can feel so
certain about these "inevitable superpredators" when
he seems incapable of naming even a single candidate.
I'm not surprised that he finds the occasional evolution of predators that
drive themselves to extinction inevitable. What's strange is the contrast to
textbook ecology -- a mutation that confers such properties should lead to
extinction (of a deme) faster than it could spread. A very homogeneous, very
panmictic population would be needed to overcome this...
