Analyse
Pääbo’s statement aligns with decades of genetic research, including his own pioneering work sequencing the Neanderthal genome. Studies confirm that non-African modern humans carry **1-4% Neanderthal DNA**, inherited from interbreeding events ~45,000–50,000 years ago in Eurasia. While this ancestry has *eroded* due to natural selection (e.g., some Neanderthal gene variants were maladaptive and gradually lost), it remains detectable in contemporary populations. His phrasing—'mix' and 'erosion over time'—is scientifically precise.
Achtergrond
Neanderthals (*Homo neanderthalensis*) coexisted with anatomically modern humans (*Homo sapiens*) in Europe until their extinction ~40,000 years ago. Genetic evidence, first published by Pääbo’s team in 2010, proved interbreeding occurred, challenging earlier assumptions of complete reproductive isolation. Subsequent studies (e.g., *Science*, 2016; *Nature*, 2021) mapped how Neanderthal DNA influences modern traits (e.g., immune responses, skin/hair features) while also being purged in certain genomic regions.
Samenvatting verdict
Svante Pääbo’s claim accurately reflects genetic evidence that early modern humans in Europe interbred with Neanderthals, with traces of that ancestry persisting today, albeit reduced over time.
