One important criticism, which dubs his theory the ‘Monkey-F******-A-Pig hypothesis’, is that there is little chance that pigs and chimps could be interfertile. The two orders of creatures, according to evolutionary theory, diverged roughly 80million years ago, a ScienceBlogs post points out.

‘[J]ust the gradual accumulation of molecular differences in sperm and egg recognition proteins would mean that pig sperm wouldn’t recognize a chimpanzee egg as a reasonable target for fusion,’ PZ Myers writes.

Furthermore, the blogger explains, while chimps have 48 chromosomes, pigs have just 38.

He adds: ‘Hybridizing a pig and a chimp is like taking half the dancers from a performance of Swan Lake and the other half from a performance of Giselle and throwing them together on stage to assemble something. It’s going to be a catastrophe.’
