So the findings indicate that the acquiring of the modern novel one may have protected us from the harmful effects of lead early on in our development, promoting complex language development and social growth. And this could have given modern humans a significant evolutionary advantage over Neanderthals, even in the presence of lead contamination. And these results have some rather important implications for understanding how environmental stresses shape the brain development during human evolution. And scientists speculate that lead exposure may have contributed to the extinction of Neanderthals around 40,000 years ago, but because of this variant we had in this gene, it allowed us to survive and to evolve. This is repeater station kilo kilo seven November. What's interesting here too is because we have language, we can organize ourselves in society, exchange ideas, and this allows us to coordinate large movements of society. And there's no evidence in the Neanderthals to do that. They might have had abstract thinking, but they couldn't translate that to each other. Maybe the reason is because they never had a system to communicate that was as efficient as our complex language. I mean, they did have ways to communicate, but not nearly as complex as our various languages.
