![]() ![]() This allele was previously only seen in modern-day humans. The team also analyzed the genes that secrete the ABO blood groups, finding a certain form of a gene called a “se” allele. It implies that the ancestors of Neanderthals, Denisovans, and Homo sapiens likely possessed these blood types too, Condemi says.Ī Neanderthal skull on display in Paris, France. This is the first time ABO blood groups have been confirmed in humans beyond modern-day Homo sapiens. What’s new - For the first time, scientists discovered that Neanderthals and Denisovans possess the ABO blood groups, which contain antigens that are important for modern blood transfusions. The effort to identify polymorphism, she tells Inverse, came with the aim to “bring a complementary view on the evolutionary history of the human lineage.” The team was also looking to identify the presence of genetic variation across Neanderthals and Denisovans, a concept known as polymorphism.Ĭo-author Silvana Condemi is the research director of the National Center for Scientific Research in France. “Blood group systems were not known in Neanderthals and Denisovans.” Like hair or eye color, blood type is inherited. ![]() The study team analyzed ancient genetic data collected by the Max Planck Department of Evolutionary Genetics to determine blood type - blood type is determined by changes in the amino acids of certain alleles. How they made the discovery - To know a person’s blood type, you don’t actually need access to their blood. These include insight into early interbreeding with Homo sapiens, a previously unknown genetic link to modern humans, and evidence of a genetic disease that may have hampered reproductive success. In a study published Wednesday in the journal PLOS One, they claim the analysis points to new clues about the origin of these humans, their health, and how their genetics influence people alive today. Scientists recently analyzed the blood types of the Denisovans and Neanderthals, two now extinct members of our genus. But more peculiarly, it’s allowed for an unprecedented look into the lives, and eventual demise, of ancient humans. Today, more than a century later, Landsteiner‘s discovery is why millions of people receive life-saving blood transfusions. ![]() This finding led to a Nobel Prize and the eventual discovery of the four specific blood types: A, B, O, and AB. In 1901, biologist Karl Landsteiner made a landmark discovery: Human blood contains different types of groups. ![]()
