CHIMPS HAVE HERITABLE g

After a half century of primatologists preferring to avoid talking about the dreaded ‘general intelligence,’ let alone showing the intercorrelations between cognitive tests run on their animals, researchers in Atlanta, Georgia (led by William Hopkins of the Yerkes National Primate Research Center) bit the bullet and reported a clear, strong and human-like g factor among 13 mental tests given to 99 chimpanzees ranging in age from 9 to 54 (New Scientist 11 vii). Hopkins et al. measured ability in four broad categories: spatial memory and ability; tool use; communication skills; and establishing causality. Tests to remember which of three beakers hid food, for example, helped measure spatial memory, while challenging chimps to obtain visible but otherwise inaccessible food by attracting attention from humans helped measure communication skills.

By combining results from all the categories, the researchers calculated values for g. And, lo, chimp g turned out to be 53% heritable – just like the g factor in man, the authors observed. (The research group had genetic and other data on the animals’ likely relatedness.) "The historical view is that non-genetic factors dominate animal intelligence, and our findings challenge that view," said Hopkins. Chimp IQ differences could not, of course, be attributed to the socio-economic differences envisaged as so crucial by Western social scientists; and being reared by humans yielded chimps no advantage in g.
