Conversely, significant rates of modern human gene flow into Neanderthals occurred—of the three examined lineages—for only the Altai Neanderthal (0.1–2.1%), suggesting that modern human gene flow into Neanderthals mainly took place after the separation of the Altai Neanderthals from the El Sidrón and Vindija Neanderthals that occurred ...
Results showed that Neanderthals have a thinner cuspal enamel that was formed in less time than in modern humans. [29] The thinner enamel in Neanderthals than in modern humans was a result of having a lower long-period line periodicity and a faster extension rate, which resulted in lower crown creation times than modern humans .

Neanderthals and Denisovans are more closely related to each other than they are to modern humans, meaning the Neanderthal/Denisovan split occurred after their split with modern humans. [ 14 ] [ 92 ] [ 138 ] [ 158 ] Assuming a mutation rate of 1 × 10 −9 or 0.5 × 10 −9 per base pair (bp) per year, the Neanderthal/Denisovan split occurred ...
The findings suggest that very early human history was complex, and modern humans likely interacted with Neanderthals — and other types of archaic humans, including the enigmatic Denisovans ...
Since the Neanderthal genome was first sequenced 15 years ago, researchers have worked to link modern humans to these archaic ancestors in a variety of ways.
Based on directly-dated Neanderthal remains, the date of Neanderthal extinction was between 40,870 and 40,457 years ago. Experts estimate that modern humans first appeared between 42,653 and ...
Since 2005, evidence for substantial admixture of Neanderthal DNA in modern populations is accumulating. [2] [3] [4] The divergence time between the Neanderthal and modern human lineages is estimated at between 750,000 and 400,000 years ago. The recent time is suggested by Endicott et al. (2010) [5] and Rieux et al. (2014). [6]
Scientists have been studying the genetic differences between archaic and modern humans since 2010, when the Neanderthal genome was sequenced for the first time.
