Here's a segment of the Morgan Freeman-narrated science show Through the Wormhole on "Is There a Superior Race?" featuring John Hawks in a spiffy hat on a recent evolution, IQ expert Linda Gottfredson, and dog intelligence guru Stanley Coren.

Unsurprisingly, the part with Prof. Gottfredson of the U. of Delaware discussing racial differences in average IQ appears to have disappeared through a wormhole. You can, however, still read the subtitles to the vanished video here.
