Here's a thought: If you didn't read the article or lack sufficient reading comprehension to know what it's about, don't comment. It has nothing to do with the so-called "paleo diet," except indirectly.
Although posting a naked link without some sort of introductory comment is also a foul. And the article does needlessly ramble a bit.
Funny how many of the people who commented on the Chronicle of Higher Education page also clearly didn't read the article, or understand the point of it. Others embodied the point.
Anyway, people aren't only delusional about the paleozoic era. Modern urban humans live in such an artificial environment that they are pretty delusional about the universe in general.
