Igniting a scientific furor, scientists say they may have found the genetic mutation that first separated the earliest humans from their apelike ancestors.

The provocative discovery suggests that this genetic twist -- toward smaller, weaker jaws -- unleashed a cascade of profound biological changes. The smaller jaws would allow for dramatic brain growth necessary for tool-making, language and other hallmarks of human evolution on the plains of East Africa.

The mutation is reported in the latest issue of the journal ...
