New hypothesis explains how human ancestors used fire to their advantage

Fire, a tool broadly used for cooking, constructing, hunting and even communicating, was arguably one of the earliest discoveries in human history. But when, how and why it came to be used is hotly debated among scientists. A new scenario crafted by anthropologists proposes that human ancestors became dependent on fire as a result of Africa's increasingly fire-prone environment 2-3 million years ago.
