Ancient DNA reveals Europe’s Neanderthals collapsed to a single surviving lineage before extinction

A new study of Neanderthal mitochondrial DNA from sites across Belgium, France, Germany, and Serbia shows that Europe hosted multiple Neanderthal mtDNA lineages until about 65,000 years ago, after which a single southwestern France–origin lineage replaced the others and spread across the continent. This led to reduced genetic diversity among Late Neanderthals and, together with climate pressures, may help explain why Neanderthals in Europe went extinct around 40,000 years ago, though researchers caution that no single cause is responsible.

Researchers Identify Humanity's Ancestral Homeland

Scientists in Australia, led by Professor Vanessa Hayes, have traced the oldest maternal line of humans using mitochondrial DNA, suggesting the ancestral home of modern humans is in southern Africa, spanning Namibia, Botswana, and Zimbabwe. This area, once home to Africa's largest lake, could have supported human life for 70,000 years. However, some experts caution against drawing definitive conclusions from genetic data alone, citing the complexity of human migration and evolution.
