Final answer:
Homo habilis were early hominins in the genus Homo and likely ancestral to Homo erectus. Olduvai Gorge is an Oldowan site that explored the remains of Homo habilis.
Step-by-step explanation:
Homo habilis were early hominins that lived between 2.5 and 1.4 million years ago in East Africa. They are considered to be the first known species in the genus Homo and were likely ancestral to Homo erectus. Although their diet is not fully understood, evidence suggests that Homo habilis were primarily herbivores.
The Oldowan site, Olduvai Gorge, explored the remains of Homo habilis. In 1960, a partial juvenile skull, hand, and foot bones were found at this location, providing important insights into the anatomy and behavior of Homo habilis.
