Ardipithecus kadabba

fossil hominin

Quick Summary

Ardipithecus kadabba is an extinct genus of early hominins that lived between 5.8 and 5.2 million years ago. Fossils attributed to Ar. kadabba have been discovered in the Awash River valley in Ethiopia. These remains include fragments of limb bones, isolated teeth, and parts of the jaw.12

While the canine tooth of Ar. kadabba has some ape-like characteristics, it lacks the interlocking honing complex seen in apes. A toe bone assigned to this species exhibits bipedal anatomy, suggesting upright walking capabilities. However, this toe bone was found in sediments younger than and geographically separate from other Ar. kadabba fossils, raising questions about its definitive classification. Ardipithecus is considered a likely ancestor of Australopithecus and provides insights into the earliest stages of human evolution.134
