Final answer:
The first hominin to leave Africa were quite possibly a species of the genus Homo, as suggested by the Dmanisi findings.
Step-by-step explanation:
The Dmanisi findings suggest that the first hominin to leave Africa were quite possibly a species of the genus Homo. The Dmanisi hominins were settled in eastern Europe around 1.85 million years ago and possibly represented a link between Homo erectus and Homo ergaster. These findings provide insights into the early migrations of hominins out of Africa.
