Data from: Larger brain size indirectly increases vulnerability to extinction in mammals

Alejandro Gonzalez-Voyer, Manuela González-Suárez, Carles Vilà & Eloy Revilla
Although previous studies have addressed the question of why large brains evolved, we have limited understanding of potential beneficial or detrimental effects of enlarged brain size in the face of current threats. Using novel phylogenetic path analysis, we evaluated how brain size directly and indirectly, via its effects on life-history and ecology, influences vulnerability to extinction across 474 mammalian species. We found that larger brains, controlling for body size, indirectly increase vulnerability to extinction by...
