Placental Mammal Diversity Exploded After Age of Dinosaurs
February 7, 2013
Researchers have reconstructed the common ancestor of placental mammals--a diverse group including animals ranging from rodents to whales to humans--using the world's largest dataset of both genetic and physical traits. In research published in the journal Science, the scientists reveal that, contradictory to a commonly held theory, placental mammals did not diversify into their present-day lineages until after the extinction event that eliminated non-avian dinosaurs.
