Step-by-step explanation:
The earliest Homo sapiens fossils were found at the Omo Kibish site in Ethiopia, which dates to about 195,000 years ago. This discovery is significant as it provides insights into the early distribution of Homo sapiens, as well as their anatomy and behavior at a time when they were beginning to exhibit modern traits. These early Homo sapiens from Omo Kibish have provided valuable information to anthropologists and paleontologists, allowing them to better understand the timeline and evolution of our species.
