A study of fossil teeth reveals that prehistoric hominids were exposed to lead for at least 2 million years, potentially influencing brain evolution. Modern humans appear to have adapted better to the toxin than relatives like Neanderthals, according to research using ancient samples and brain organoids. However, some experts question the extent of this exposure and its evolutionary implications.
