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 ?

It’s cooking smoke for Pete’s sake. Sometimes the PC crowd really gets to me.

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?
To: SunkenCiv
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?

Where was the EPA when we needed them back then to put an end to these backyard....err...cave barbeques! They could have nipped all this manmade global warming in the bud!
To: SunkenCiv
“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 priceand we find possibly the first evidence of this at Qesem Cave 400,000 years ago.”
...
The tradeoff seems to offer far more positives than negatives.

Knock. Knock nOOb. You've come to the wrong place to try to denigrate SV....a longtime, popular chronicler of many fascinating threads. Once you've been around for mite longer....you may have earned the privilege. Go troll someone else. THX

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