In an article published in Nature Ecology & Evolution, an international team of researchers analyses the genome of an almost complete skull first discovered in Zlatý Kůň, Czechia in the early 1950s and now stored in the National Museum in Prague. The segments of Neanderthal DNA in its genome were longer than those of the Ust’-Ishim individual from Siberia, the previous oldest modern human sequenced, suggesting modern humans lived in the heart of Europe more than 45,000 years ago.
