At UMass Amherst, skulls tell the tale of evolving bats

UMass Amherst news office has a release on a study looking at bats skulls:

“This study conducted during the International Year of the Bat offers a clear example of how the evolution of new traits, in this case a skull with a new shape, allowed animals to use new resources and eventually, to rapidly evolve into many new species,” (Elizabeth) Dumont (of UMass) says. “We found that when a new ecological niche opened up with an opportunity for bats that could eat hard fruits, they shifted their diet significantly, which in turn led to the evolution of new species.”
