I've always enjoyed Popular Science's articles, but it's very rare indeed that something doesn't get in the way of my thoroughly enjoying them and this article is no exception.
Whoever wrote the clunky sentence "We tend to not think of lizards as particularly intelligent, and many aren't--but the scary dinosaur-like monitor lizard is highly intelligent" needs to attend a decent remedial English class. "We tend to not think . . ."? Why not "We don't tend to think . . . "?
Such sloppy fourth-grade writing is particularly annoying when it comes from a supposedly professional writer. Why would anyone pay for "We tend to not think . . ."? Who would have the chutzpah to accept money for having written that?
Education shouldn't focus on science to the detriment of all other areas of learning. Communicating effectively about science as important as science itself.
