Dinos loss, was not mammals' gain.



The big dinosaur extinction of 65 million years ago
didn't produce a flurry of new species in the ancestry
of modern mammals after all, says a huge study that
challenges a long-standing theory.

Scientists who constructed a massive evolutionary
family tree for mammals found no sign of such a burst
of new species at that time among the ancestors of
present-day animals.

Only mammals with no modern-day descendants showed
that effect.


So it seems that dinosaurs weren't keeping mammals
down afterall (well, at least in terms of species

Time to look to the real culprit...the man. >:)
