Rabbit-proof hoof: Ungulates suppressed lagomorph evolution

Summary:
Rodents and rabbits are sister groups, but while rodents have diversified to over 2,000 living species and an enormous range of body sizes, lagomorphs (rabbits, hares, and pikas) are limited to fewer than 100 relatively small species. A new study shows, surprisingly, that competition with ungulates -- hoofed mammals -- intensified by climate change, are to blame for the lagomorphs' limited diversity
