That research doesn't disprove current theory either. Cultures grow through diffusion and the introduction of new ideas and technology. How do they know that the Neanderthals didn't take it from modern humans?
Even if they did just take the tech from modern man, the fact that they used it would seem to hurt the theory that modern man's superior tech was a reason why they survived and Neanderthals died. Modern man invented it, but if both use it the benefit should be negligible shouldnt it? And it sounds like the article is saying they had different technologies, but there is no evidence that modern mans is necessarily better or more efficient. So it isnt just a matter of Neanderthal taking a superior tech from modern man, but having his own that's equivalent.
Not necessarily. We don't know how much sharing or even stealing took place, if it happened at all. Furthermore, it could very well be that Neanderthals tried to mimic modern man's technology, maybe they found a way to even improve it. Here's a plausible explanation. Maybe modern man enslaved Neanderthals and some of them escaped, going back to their people, with the tools or a familiarity with them. It could also very well be that Neanderthals were able to take some of modern man's technology, maybe even invent their own, but that modern man was more consistent in his creativity in adapting to his surroundings. All of this is conjecture and I stated it doesn't prove or disprove either way.
My understanding was that the narrower blades used by the early modern Homo Sapiens were more effective in throwing spears. This allowed them to hunt large game with a lower risk of injury and also a higher success rate.
