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?
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?
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!
“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.”
