Living fast may have helped mammals like ‘ManBearPig’ dominate
Such a fast-paced lifestyle may have helped early mammals get big fast after the dinos’ demise
In the wake of the dinosaurs’ demise, a bizarre beast that some researchers have nicknamed “ManBearPig” lived life in the fast lane. This sheep-sized mammal — which sported five-fingered hands, a bearlike face and the stocky build of a pig — gave birth to highly developed young. And those young grew up much faster than expected for an animal as massive as ManBearPig, new fossil analyses show.
That combination of long gestation and quick aging may have led to many rapid generations of bigger and bigger babies, researchers report online August 31 in Nature. Such an approach to life could help explain how some mammals took over the world after the dinosaur doomsday.
