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. The part of the DNA that is involved in Rh status is tricky to read and we haven't yet been able to figure it out in Neanderthals. Q: Given the three main blood types A, B, and O, is it possible that these exist due to the original genetic admixture of CroMagnons with Neanderthals and separately with Denisovans? For years experts believed all neanderthals had the blood type O. The influence of blood groups on human inheritance was looked at, and it was explained that while the nuclear DNA (the main DNA considered in inheritance) of Basques might well have more Neanderthal inheritance than average, their mitichondrial DNA (passed on directly from mother to child) might have had all Neanderthal components bred out. It's not easy to find out which human genes matter to Covid-19 susceptibility. According to a study published Wednesday in the journal PLOS ONE, Neanderthals possessed a blood type that rendered them more susceptible to infectious diseases, resulting in high infant mortality.

When scientists tested whether Neanderthals had the O blood group they found that two Neanderthal specimens from Spain probably had the O blood type, though there is the possibility that they were OA or OB (Lalueza-Fox et al. Some of the evidence posited for this comes from studies of the ABO blood group and Rh factor of the populations in question. Neanderthals might have made good blood donors. That is absolute rubbish of course. 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. You do have Neanderthal ancestors, or you wouldn't have O neg blood. The gene that produces the ABO blood system is polymorphic in humans, meaning that there are more than two possible expressions of this gene. . Since 2005, evidence for substantial admixture of Neanderthals DNA in modern populations is accumulating. A new analysis of Neanderthal genomes suggests the ancient blood that once pumped through this long-extinct population of archaic humans had more in common with modern human blood than scientists realized.
