Two Neanderthal children from 250 kya showed lead exposure, and much else

Based on an analysis of their teeth:

Two 250,000-year-old teeth from two Neanderthal children revealed that both of them were exposed to lead twice during their short lifetimes, the first known case of lead exposure in Neanderthals…

“Teeth record environmental variation based on the climate, even where you’re growing up,” said Tanya Smith, lead author of the study and associate professor at Griffith University. “That’s possible because when you’re growing, your teeth you actually lock in a record of the chemistry of the water and the food that you’re eating and drinking. Because teeth have these tiny timelines, we can relate the chemistry to the growth to calculate ancient climate records. We can’t do that with any other element of the body.”

They were able to determine that one of the Neanderthal children was born in the spring and that both children were more likely to be sick during the colder winter seasons. They lived through more extreme seasons with a greater variation in temperature than the modern human child who was also studied.Ashley Strickland, “Earliest discovery of lead exposure found in Neanderthal children” at CNN

Neanderthals were not supposed to suffer from lead exposure. Were they trying to work with lead?: Lead is a highly lustrous, bluish-white element that makes up only about 0.0013 percent of the Earth’s crust, according to the Jefferson Lab. It is not considered rare, however, since it is fairly widespread and easy to extract.

Although lead has been phased out of many of its previous uses, this non-corrosive metal is actually quite useful in products that hold or touch highly acidic substances. For example, lead is used to line tanks that hold corrosive liquids, such as sulfuric acid. It is also used in lead-acid storage batteries, such as those found in automobiles. More.

The causes of the children’s deaths are unknown but one was nursed for two and a half years.

So much more information is coming to light about Neanderthals and other vanished peoples that
it’s getting harder than ever to find the missing link. In any good Darwinian scheme, someone must be the subhuman. Otherwise, there is no beginning to human history. But stories, sure, there will be plenty more stories.

That’s speculation of course, but the difference is that if evidence is in play, it’s no longer free-form speculation.

    aligns well with Torah Discovery Chronology where not only an iron age prior to the 1656 anno mundi extinction event ‘Mabul’ impacts global flood year by Tubal Cain.., but our RCCF hypothesis that the dispersion from Bavel by the 1996 end of The ice age was due to cumulative lead brick strengthening agent additive exposure.
    By Akkadian King Nimrod where the state was of primary importance, and few exceptions to the public works project that was Migdol (Tower of) Bavel, traces of lead would have been brought home by those who did not wash, and been in the air about furnace where the bricks were backed.
    Per RCCF Neanderthal were part of our normal spectrum of diversity, and partly explained by our low entropy atmosphere, so slower maturity, longer life spans and greater size potential.
    Refererence RCCF framework for understanding science.
