Expert's answer

Homo erectus is a fossil species of people considered as the direct ancestor of modern humans. Homo erectus actively manufactured stone tools and used fire.

The tools made by a Homo Erectus were pointed at one end and performed at the same time piercing and cutting functions. Such tools characterized almond-shaped form are called the “Ashelian chopper.” Hunting tools were processed on both sides. They were extremely common in the early Paleolithic. Making a chop required significant mental abilities and production skills because it is necessary to process the stone in such a way as to obtain weapons of a given shape and size. The master possessed specific skills in stone processing and a clear view of the final type of product.

Homo erectus learned to ignite and maintain fire. Most likely, they received fire during a forest fire and for centuries supported it in caves. The use of fire affected the morphology of Homo erectus. Food processed by fire is easier to chew, which has reduced the size of the jaws. Mastering fire influenced a person’s progress, developed his mind and helped to raise the standard of living in primitive society. On the other hand, Homo erectus could use fire to drive animals into open space, where it was easier to reach them with spears. They also learned to use fire as a source of heat, as Homo erectus began to migrate to colder regions, and fire became necessary.
