Did an Exploding Comet Doom Early Americans?

New Scientist outlines a new theory on the demise of the Clovis people in the southwest US over 10,000 years ago. A group of 25 researchers speculates that a comet exploded over ice-covered Canada 12,900 years ago and triggered a firestorm across North America that not only wiped out the Clovis people but also forced a number of large land mammals into extinciton and kicked off the Younger Dryas climate change. However, geologists are pretty conservative folks, according to the article, and some of them are not buying it.

According to Wikipedia, the Younger Dryashttp://en.wikipedia.org/wiki/Younger_Dryas was not preceeded by the Older Wetass. It was a short period of time between the Pleistocene and the current Holocene climate eras.

So ... when were the Dumas and Smartas periods?

That's why we need to become highly active in do-it-yourself genetic engineering. Then we can grow our own females in our basements. And our genetically engineered females will be superior to natural ones, as we can design them to be thin, beautiful, bisexual, and only interested in geeks (and other hot women).
