From my physical anthropology class, the Neanderthal that was used to identify the species early on was suffering from arthritis, so that the idea of cavemen who were thought to be thuggish, constantly stooped-over brutes weren't that distinguishible from modern humans. Genetics seems to have shown that they are indeed a seperate kind of primate, but I don't know if that's been conclusive or not.
Jack Chick is a pretty skilled cartoonist, even if his theories are absolutely insane. I read a scathing review of his life in an American magazine called The Imp that talked about his strange existance, and how all he does is work, check his mail box, and go home. And, Chick also apparently loves horror movies & biker culture, which gives him plenty of ideas...
Also, the guy who did the admittedly great art on the Crusaders comic (the only other Chick artist in his stable) was actually making, all by himself, an animated feature in true Chick style about apokolipse and the Chick crusades that was going to be projected on the sides of buildings and other strange kind of guerella selling tactics. Apparently, though, the guy suufered a stoke a few years back that has made the job alot harder, so I don't know if it will every be finished.
