One of the challenges of working with ancient DNA samples is that damage builds up over time, breaking the double
The DNA study suggests that the Neanderthals did not really disappear, but were absorbed into the modern human population.
Neanderthals may not have truly gone extinct, but instead may have been absorbed into the modern human population. That’s one
