Tony: More likely a sign of scientist misinterpreting the evidence. There is already enough evidence to show that these 'different species' actually fall within the same range of deviations found in modern humans. All this other is just speculation to make it fit with Darwinian evolution. You wouldn't call an African subhuman because they still use spears and bolo's would you? This is essentially what they are doing here.-There is more and more evidence that the Neanderthals were quite bright and advanced.
