The fossil teeth show that Neanderthals and other ancient relatives got exposed to a lot of lead from the environment.
And Allison Miotry of the University of California, San Diego, thinks this could have affected human evolution.
He studies brain development genes, including one gene that's slightly different in Homo sapiens compared to Neanderthals.
In the journal Science Advances, he and some colleagues say that pressure could have come from lead.
Lab tests show that brain cells with the human version of the gene had some protection against lead, while brain cells with the Neanderthal version didn't.
