400,000-year-old dental tartar provides earliest evidence of manmade pollution
Phys dot org ^ | June 17, 2015 | Tel Aviv University

In what Prof. Barkai describes as a "time capsule," the analysed calculus revealed three major findings: charcoal from indoor fires; evidence for the ingestion of essential plant-based dietary components; and fibers that might have been used to clean teeth or were remnants of raw materials.

"Prof. Karen Hardy published outstanding research on the dental calculus of Neanderthals from El Sidron cave in Spain, but these dated back just 40,000-50,000 years—we are talking far earlier than this," said Prof. Barkai. "This is the first evidence that the world's first indoor BBQs had health-related consequences," said Prof. Barkai. "The people who lived in Qesem not only enjoyed the benefits of fire—roasting their meat indoors—but they also had to find a way of controlling the fire—of living with it.

"This is one of the first, if not the first, cases of manmade pollution on the planet. I live near power plants, near chemical factories. On the one hand, we are dependent on technology, but on the other, we are inhaling its pollutants. Progress has a price—and we find possibly the first evidence of this at Qesem Cave 400,000 years ago."

charcoal from indoor fires; evidence for the ingestion of essential plant-based dietary components; and fibers that might have been used to clean teeth or were remnants of raw materials.

Toothpaste, food stuck in teeth, and fibers from a toothbrush.

How does that prove manmade pollution and did global warming start 400,000 years ago ?

So Neanderthals were making fires 400,000 years ago, but we’re still expected to believe that they were all stupid back then and had no ability for abstract thought?

Please explain how the date was arrived at. “400,000-year-old dental tartar” —exactly, to the year? Lastly, how do they know it was tartar? Did they have teeth back then that accumulated tartar through a diet the same as our modern diet? What was the diet? What thing did these teeth with “tartar” belong to? Human, animal, and how was that determined?

400K ago... while I have more confidence than most in our ancestors’ inventiveness, it doesn’t seem unlikely that they cooked over an open fire more often than not, so the charcoal was probably *in* the food. :”)

You again. You never answer any question I pose, just reply with insults. As per your homepage, you claim to believe in “catastrophism.” Yet none of you posts mention anything about it. Who are you trying to fool? Crack a book and tell me where you get your belief.

I don’t claim to “believe in” anything on my homepage. IOW, you’ve just lied. No surprise there. And quit trolling, then acting like the aggrieved party.

Why didn’t they just use a microwave?

...

The tradeoff seems to offer far more positives than negatives.

Was the tartar from Harry Reid's teeth?

Prehistoric man was ‘supposed’ to be a vegan. His sin of eating meat has been killing the planet a verrrrry long time.
