The new results suggest that neanderthals and modern humans mixed in modern-day europe “what’s exciting about this is that it is evidence that neanderthal mixture occurred in europe as well,” said reich and looking even further into the future, ancient-dna researchers will be able to elucidate even more about early human evolution. Relationship of neanderthals to modern humans after extracting ancient dna from the 40,000-year-old bones of neanderthals, scientists have obtained a draft sequence of the neanderthal genome, yielding important new insights into the evolution of modern humans. Neanderthals were significantly shorter and stockier than modern humans, with much broader rib cages and pelvises to give some perspective, the average height for a man in the usa is 176 metres conversely, based on the fossil records available, the average height for a neanderthal was just 16 metres.
The neanderthal genome project published papers in 2010 and 2014 stating that neanderthals contributed to the dna of modern humans, including most humans outside sub-saharan africa, as well as a few sub-saharan africa's populations, through interbreeding, likely between 50,000 and 60,000 years ago. It indicated that neanderthal and modern human brains were the same size at birth, but that by adulthood, the neanderthal brain was larger than the modern human brain they had almost the same degree of encephalisation (ie brain-to-body-size ratio) as modern humans. Neanderthals thrived in europe from 350,000 to about 40,000 years ago, but disappeared after early modern humans showed up from africa so how did these neanderthal genes get into modern humans.

A causality between millennial-scale climate cycles and the replacement of neanderthals by modern humans in europe has tentatively been suggested however, that replacement was diachronous and occurred over several such cycles a poorly constrained continental paleoclimate framework has hindered identification of any inherent causality. More essay examples on dna rubric according to green, krause et al in their nature article of 2006 ‘comparison with the human and chimpanzee genomes reveals that modern human and neanderthal dna sequences diverged on average about 500,000 years ago. Neanderthals were shorter in height than humans yet had longer limbs and a bigger skull and brain their position was upright but closer to the one standing primates adopt, rather than that of humans.

Neanderthals and humans were not in direct competition for too long, because neanderthals disappeared earlier than once thought, according to one study published in may of this year in the. The neanderthals are very closely related to modern humans, differing in dna by only which, however, is twice that of the widest dna gap found among contemporary humans reconstructions of neanderthal man. Gene flow between neanderthals and early modern humans may have been a one-way street, researchers have found while the presence of neanderthal dna in modern human genomes is well attested.
Neanderthals and fossil homo sapiens living at the same time had equal brain volume a new study shows, though, that neanderthals had larger eye sockets – and a larger brain area devoted to sight – than in modern humans.
