“Although Homo heidelbergensis has generally been seen as a precursor to Neanderthals, its precise relation to us has been less clear. This fossil analysis is some of the most compelling evidence yet that we can in fact trace an evolutionary lineage back through Homo heidelbergensis.”
From a 400,000 year-old skull found in Ceprano, Italy, scientists believe they may have locked down humankind’s parent species. “The idea is that, aided by the favorable climates of the Middle Pleistocene starting around 780,000 years ago, Homo heidelbergensis spread far and wide throughout the Old World. Around 400,000 years ago, this mobility began to decrease and Homo heidelbergensis became more isolated, paving the way for the clear emergence of Neanderthals and modern humans in Eurasia and Africa respectively.“
