Step-by-step explanation:
The hominin type that lived around 1.5 million years ago and was the first to leave Africa, entering Asia and Europe, is Homo erectus. This species, an early type in the genus Homo, evolved approximately 1.9 million years ago in East Africa and eventually migrated into Eurasia. With features more similar to modern humans, Homo erectus was larger in size compared to its predecessors and had a larger brain capacity. They made significant advancements such as the use of fire and tools, and they adapted to various environments during their migrations out of Africa.
