8. Ancient (Early) Technology Tools Tools Weapons Weapons Flint spear, circa 100,000 BC The history of technology is at least as old as humanity. Some primitive forms of tools have been discovered with almost every find of ancient human remains dating from the time of primitive humans. The earliest technologies turned easily found natural resources (such as rock, wood and other vegetation, bone and other animal byproducts) into simple tools.

10. And what perhaps (maybe) is the earliest example of technology? Humans use of Humans use ofFIRE The use, and then mastery, of fire (circa 1,000,000 - 500,000 BCE was a turning point in the technological evolution of humankind, affording a simple energy source with many profound uses. Perhaps the first use of fire beyond providing heat was the preparation of food. This enabled a significant increase in both vegetable and animal sources of food, while greatly reducing perishability (being able to spoil).
