Eating raw meat and making stone tools may be behind the smaller teeth and faces of humans compared with their ancient relatives.
Meat and tools, not the advent of cooking, was the trigger that freed early humans to develop a smaller chewing apparatus, a study suggests.
This in turn may have allowed other changes, such as improved speech and even shifts in the size of the brain.
The authors conclude that cooking became commonplace much later.
Prof Daniel Lieberman and Dr Katherine Zink from Harvard University have published their work in the journal Nature.
