Fossil tooth reveals early human ancestors had an extended growth phase, challenging views on evolution.

This suggests that early Homo species had an extended growth phase, challenging previous beliefs that longer childhoods only developed around 300,000 years ago. The study used advanced imaging techniques to analyze the tooth's growth patterns, offering insights into human evolution.
