Prehistoric technology is technology that predates recorded history. History is the study of the past using written records. Anything prior to the first written accounts of history is prehistoric, including earlier technologies. About 2.5 million years before writing was developed, technology began with the earliest hominids who used stone tools, which they may have used to start fires, hunt, and bury their dead.
There are several factors that made the evolution of prehistoric technology possible or necessary. One of the key factors is behavioral modernity of the highly developed brain of Homo sapiens capable of abstract reasoning, language, introspection, and problem solving. The advent of agriculture resulted in lifestyle changes from nomadic lifestyles to ones lived in homes, with domesticated animals, and land farmed using more varied and sophisticated tools. Art, architecture, music and religion evolved over the course of the prehistoric periods.
