Who Were Homo Ergaster?
Homo ergaster is one of the earliest members of the human family tree, known as the genus Homo. Scientists are still discussing exactly how they fit in. Many believe H. ergaster was a direct ancestor to later human types. These include Asian Homo erectus, Neanderthals (Homo neanderthalensis), and even modern humans (Homo sapiens). Some experts think H. ergaster was simply the African version of Homo erectus. Homo erectus was the first human species to spread out of Africa.
What Does Their Name Mean?
The name ergaster means "workman" in Latin. This name was chosen because Homo ergaster developed advanced stone tools. These tools are part of what is called the Acheulean tool industry. The most famous tool they made was the hand axe.
Where Did They Live?
Homo ergaster lived in eastern and southern Africa. Their time on Earth happened during the first part of the Pleistocene epoch. This was a period when the Earth's climate became much cooler. It was also the start of the ice ages.
These big climate changes affected the land in Africa. The large rainforests began to shrink. At the same time, wide open savannahs and open forests grew larger. Homo ergaster was well-suited to live in these new, more open environments.
