Unbelievably, I'm actually enjoying this caveman and primate-related human evolution anthropology-type stuff. It's all very interesting, all this business with signing chimps, Theory of Mind and whether cave paintings can be taken as a reliable indicator that a group of cavemen is using verbal language. Of course, my brain still objects logically on the grounds that it's all terribly terribly subjective, and unlike developmental biology, transcription factors or biochemical pathways, it's almost impossible to measure or quantify accurately. But it's interesting, nonetheless.
