Results vary depending on methodology used, but commonly cited numbers say that modern humans are 99.9% identical in DNA.
Neanderthals were 99.7% identical and apparently interbred with humans, making Neanderthals the same species as humans.
By contrast chimpanzee DNA is around 96% identical to humans, cannot interbrede and so are classified as a separate genus of great ape.
That doesn't stop some from trying...

It would be nice if they gave the methodology and data instead of just the opinion or theories. There are other people out there with opposite opinions and just as many facts. When I see an article I can not tell if it is a hit piece or a theory with same methodology as global warming.
