Termites shape and are shaped by their mounds

Termite construction projects have no architects, engineers or foremen, and yet these centimeter-sized insects build complex, long-standing, meter-sized structures all over the world. How they do it has long puzzled scientists.

A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.
