Ancient lead exposure may have influenced how our brains evolved

Does lead poisoning have to with how our brains evolved? That is what Darwinists acclaim.  

 Lead poisoning isn't just a modern phenomenon: fossil teeth show signs that it affected ancient hominids, and Homo sapiens may have coped better than our close relatives.

Prehistoric hominids have been exposed to poisonous lead for at least 2 million years, a study of fossil teeth suggests, and modern humans may have evolved to cope with the toxic metal better than our ancient relatives. That is what Darwinists say, Hominids means ape men.

Lead poisoning has long been thought to be a uniquely modern problem tied to industrialisation, poor mining practices and its use as an additive in fuel, which has been phased out since the 1980s.

It is particularly dangerous for children, impacting their physical and mental development, but it can also cause a range of severe physical and psychological symptoms in adults.
