The history of technology is at least as old as humankind, if not older. Primitive too

ls have been discovered with almost every find of ancient human remains. Archaeologists (考古学家)have uncovered tools made by humanity's ancestors more than two million years ago, and the earliest direct evidence of tool usage, found in the Great Rift Valley, dates back to 2.5 million years ago. The hunter-gatherer lifestyle, characteristic of the Lower Paleolithic era, involved a limited use of technology, and the earliest tools, were developed to aid early humans in that role.

The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of mankind. The exact date of its discovery is not known; evidence of burnt animal bones at the Cradle of Humankind suggests that the domestication of fire occurred before 1,000,000BCE; scholarly consensus indicates that Homo erectus had controlled fire by between 500,000BCE and 400,000BCE. Fire, fueled with wood and charcoal, allowed early humans to cook their food to increase its digestibility, thereby improving its nutrient value and broadening the number of foods that could be eaten.

Other technological advances made during the Paleolithic (旧石器时代的)era were clothing andshelter; the adoption ofboth technologies cannot be dated exactly, but they were key to humanity's progress.

As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as 380,000BCE, humans were constructing temporary wood huts. Clothing, adapted from the fur and hides of hunted animals, helped humanity expand into colder regions; humans began to migrate out of Africa by 200,000BCE and into other continents.
