This means Neanderthal blood not only came in the form of blood type O - which was the only confirmed kind before . al., 2016) indicates that the hybrid children were less fertile, as the prevalence of Neanderthal genes on the X chromosome is fewer than those found on the autosomal (non-sex) chromosomes. Neanderthal genes. Jan Bartek - AncientPages.com - Learning more about the Neanderthals and Denisovans is significant if we want to understand how these extinct species are related to modern humans. Neanderthal, (Homo neanderthalensis, Homo sapiens neanderthalensis), also spelled Neandertal, member of a group of archaic humans who emerged at least 200,000 years ago during the Pleistocene Epoch (about 2.6 million to 11,700 years ago) and were replaced or assimilated by early modern human populations (Homo sapiens) between 35,000 and perhaps 24,000 years ago. Neanderthal and Denisovan blood confirms its African origin. The Neanderthal individuals also had blood type alleles associated with increased vulnerability to diseases affecting fetuses . Silvana Condemi of the Center National de The evidence (Sankararaman, S. et. The Scotland's DNA project, led by Edinburgh University's Dr Jim Wilson, has tested . While it has long been assumed that Neanderthals had type O blood, like chimps, who all have type A, and gorillas, who all have type B, the researchers discovered that these ancient hominins . "But for Neanderthals living in cold areas of Europe, coming into contact with dangerous animals all the time as they were hunting them, being able to quickly clot blood when you got a cut could . Rh negatives are more deeply affected by the disease Toxoplasma gondii, an older post on this blog show how some scientists were even trying to make out that Rh negative blood is the result of the disease.

Since 2005, evidence for substantial admixture of Neanderthals DNA in modern populations is accumulating. One is on Chromosome 9 and includes ABO, a gene that determines blood type. About 1.3 percent of 23andMe research participants with type O blood tested positive for COVID-19. While it was long assumed that Neanderthals all possessed blood type O, a new study of previously sequenced genomes of three Neanderthal individuals shows polymorphic variations in their blood, indicating they also carried other blood types found in the ABO blood group system An old article claiming that .
