Mutation linking jaw to brain sparks human origin debate
A Penn and Children’s Hospital team reports a genetic mutation that may have anchored a larger jaw to the skull, enabling bigger brains, tool making, and language. The Nature study, praised by some and challenged by others, notes the mutation persists in all humans while nonhuman primates retain the original jaw. Critics call the claim controversial and potentially counter to evolution.
