Rethink the Foundations of Our Models
Modern human evolution models rely on adding multiple mixture events to fit genetic data, akin to ancient astronomical models needing epicycles to explain celestial movements.

The standard model posits a separation between modern humans and an ancestral group leading to Neanderthals and Denisovans around 500,000 to 750,000 years ago, yet reliance on increasingly complex adjustments indicates a need to reevaluate the underlying assumptions of these evolutionary frameworks.
