From History: 440,000 Years Ago (+/- 40,000 years)
The Neanderthal–Sapien last common ancestor likely emerged about 440,000 years ago. A time of a complex transitional phase possibly involving Homo heidelbergensis, Homo antecessor, or a population blending traits from both.
Extreme isolation preserves history—but it also creates vulnerability. The Sentinelese remind us that human populations evolved under vastly different conditions, and immunity is not universal. From a scientific standpoint, their existence proves modern human intelligence is at least 50,000 years old.
Evolution is not about desire, nor is it a contest of strength, or intellect. It’s about reproductive success. The individuals, and species, that possess traits best suited for the current environment are more likely to survive, and to pass on those traits. Over millennia, these traits accumulate, leading to races, sub-species, and eventually separate species unable to interbreed.
For most of human history, the cosmos was not something we studied from afar—it was something we lived beneath. With only the naked eye, our ancestors tracked patterns, told stories, and searched for meaning in the sky. The universe before the telescope was intimate, mysterious, and profoundly human.
Africa doesn’t just appear at the start of human history—it is the start. Migration, adaptation, and interbreeding shaped who we became, but they all began from a single ancestral root.
Divide the lower period into three ages: Stone, Fire, and Cultural. Divide the middle period into two ages: Symbolic and Cognitive. Finally, redefine the upper as “prehistory” and end it when our stories start: about 4,000 BCE.
Our cognitive foundation settled long before cities, scripture, or science. The same mind that painted caves now designs spacecraft. Technology changes rapidly; human nature changes slowly. Much of modern conflict is ancient psychology wearing modern tools.
“Done.” Refresh for another set.
