Summary
This article discusses the 4.4-million-year-old fossil skeleton named Ardi (Ardipithecus ramidus), which predates the famous Lucy fossil by a million years. Ardi may hold the key to understanding when our ancient primate ancestors first transitioned from climbing trees to walking upright on two feet. The fossil provides crucial evidence about the evolutionary step that turned ancient climbers into early walkers, shedding light on a pivotal moment in human evolution.
