L_1_02 — Interbreeding Events & Genetic Discontinuities

Ancient DNA has established that late human evolution was not a simple replacement story. Expanding populations of Homo sapiens interbred with Neanderthals and Denisovans, and at least one direct first-generation hybrid

L_1_08 — Denisovans — Archaic Hominin Deep Dive

Denisovans are an extinct group of archaic hominins identified primarily through ancient DNA analysis rather than traditional fossil morphology — making them history's first hominins to be discovered by genetics. In 2010

L_1_16 — Denisovan Genetics and Legacy

The Denisovans — an extinct group of archaic humans first identified in 2010 from ancient DNA extracted from a finger bone fragment found in Denisova Cave, Altai Mountains, Siberia (~41,000 years old) — represent one of
