Man's ability to digest starchy foods like the potato may explain our success on the planet, genetic work suggests.
According to current evolutionary theory, man evolved in Africa, whereas the potato evolved in South America. The two were not destined to meet until long after human beings had evolved their ability to digest starch.
Pedantic, I know, but the next thing you know, the tabloids will be claiming that we evolved from chips, not chimps.
(And yes, I know we didn't evolve from chimps, but the tabloids probably don't.)
