Early history of Neanderthals and Denisovans.

چکیده
Extensive DNA sequence data have made it possible to reconstruct human evolutionary history in unprecedented detail. We introduce a method to study the past several hundred thousand years. Our results show that (i) the Neanderthal-Denisovan lineage declined to a small size just after separating from the modern lineage, (ii) Neanderthals and Denisovans separated soon thereafter, and (iii) the subsequent Neanderthal population was large and deeply subdivided. They also (iv) support previous estimates of gene flow from Neanderthals into modern Eurasians. These results suggest an archaic human diaspora early in the Middle Pleistocene.

Discovery of Oldest DNA Scrambles Human Origins Picture
Scientists reveal the surprising genetic identity of early human remains from roughly 400,000 years ago in Spain. The bones were first thought to belong to European Neanderthals, but analysis showed they are genetically closer to the Siberian Denisovans. Analysis of the bones challenges conventional thinking about the geographical spread of our ancient cousins, the early human species called Ne...
متن کاملNeanderthals and Denisovans as biological invaders.
Humans stand out among our close primate relatives as effective biological invaders. Our recent history has included range expansions into remote and harsh geographic regions, and invasions by some populations into areas long occupied by others. Historians tend to frame these events as a story of technological and economic progress, while admitting that disease sometimes plays a central part—a ...
متن کاملSmall Amounts of Archaic Admixture Provide Big Insights into Human History
Modern humans overlapped in time and space with other hominins, such as Neanderthals and Denisovans, and limited amounts of hybridization occurred. Here, we review recent work that has identified archaic hominin sequence that survives in modern human genomes and what these genomic excavations reveal about human evolutionary history.

Her approximately 3-billion-letter nuclear genome, reported in this issue of Nature, now provides a more telling glimpse into this mysterious group. It also raises previously unimagined questions about its history and relationship to Neanderthals and humans. “The whole story is incredible. It’s like a surprising ...
متن کاملAncient DNA and human history.
We review studies of genomic data obtained by sequencing hominin fossils with particular emphasis on the unique information that ancient DNA (aDNA) can provide about the demographic history of humans and our closest relatives. We concentrate on nuclear genomic sequences that have been published in the past few years. In many cases, particularly in the Arctic, the Americas, and Europe, aDNA has ...
