Modern humans left Africa about 65,000 years ago and along the way were fornicating with other human species oldest species that they found in Europe and Asia, such as the Neanderthals. Two Swedish scientists now maintain that the genetic fingerprint of those prehistoric intercourse explains the greater fragility of some current citizens against the new coronavirus. “The main genetic risk factor for suffering from the severe form of Covid-19 is inherited from Neanderthals,” conclude the two researchers, highly respected in their field.
