Study Pretty Much Irrefutably Shows Cats are Dumber than Dogs(!)
by Josh Clark | November 30, 2010
Having long suspected it, I was heartened to hear that cats are less intelligent than dogs are. Yes. Ahhh. Bask in it.
Far less, actually, at least in relation to the correlation between brain size and sociability. This small brain size is, it appears, why cats are aloof, say researchers at Oxford University’s Institute of Cognitive and Evolutionary Anthropology, a group who are not known to be slouches when it comes to compiling reliable and solid data that dog people can reasonably gloat over.

One advantage of being as old as the New York Times is, is the fact that you have a really deep archive. And with that archive on the Internet, people can explore it and find all sorts of things.

Go back just a few years further and you find this amazing, detailed review of Darwin’s Origin of Species from 1860…
I recently wrote an article about the Sentinelese, who are, arguably, the most awesome people on the planet. Chances are pretty good, however, that you’ve never even heard of them. So just what makes them so crazy-cool and how have they been secretly keeping it under wraps all this time?
