 Asunto: Climate change and mountain building led to mammal diversity patterns
| Travel   from the tropics to the poles, and you'll notice that the diversity of   mammals declines with distance from the equator. Move from lowland to   mountains, and you'll see diversity increase as the landscape becomes more   varied. Ecologists have proposed various explanations for these well-known   "biodiversity gradients," invoking ecological, evolutionary and   historical processes |
