Prehistoric Mammal Spinolestes in the Cretaceous-Period Las Hoyas Wetland 

A discovery about the dark fur of early mammals confirms long-held theories about their evolutionary and ecological behavior.

Prehistoric Mammals' Dark Fur Was Key to Survival

A hamster-sized primate from Madagascar, the fat-tailed dwarf lemur is our closest genetic relative known to hibernate. They also tend to live longer than you’d expect given their size. New research reveals a potential anti-aging mechanism within their cells. (Image Credit: David Haring, Duke Lemur Center)
