The fact that sequenced Neanderthal genome parts are three times as different from the human genome as the least related humans are to each other is strong evidence that Neanderthals and modern humans are separate species. This level of genetic difference would not be expected if they were simply subspecies or populations of the same species. The other options do not provide as strong of evidence for separate species status. A) The burial of a Neanderthal with flowers is interesting but does not necessarily indicate separate species status. B) The same mutation in different species does not necessarily indicate separate species status. D) The distribution of Neanderthal remains is consistent with separate species status, but again, it is not definitive. E) The coexistence of Neanderthals and Cro-Magnons is interesting but does not necessarily indicate separate species status.
