Early Cognitive Foundations (2.5 million - 250,000 years ago)

Overview

The Early Cognitive Foundations period represents humanity's first major intellectual developments, marking our species' initial departure from purely instinctual behavior toward more complex cognitive processes. This crucial period laid the groundwork for all subsequent human intellectual advancement.
