When Did Ancient Humans Realize S** Causes Babies

For most of human history, ancient humans did NOT know that sex causes babies. Because pregnancy only becomes visible weeks or months after conception, prehistoric humans couldn't connect the two events — a challenge anthropologists call the "delayed causation" problem. Many early cultures explained pregnancy through spirits or ancestors instead of biology, and the sex–pregnancy link wasn't scientifically confirmed until the 1800s. This video traces exactly when — and why — it took our species roughly 300,000 years to understand where babies come from.
