more about watson:
But despite serving for 50 years as a director of the Cold Spring Harbor Laboratory on Long Island, considered a world leader in research into cancer and genetics, Dr Watson has frequently courted controversy with some of his views on politics, sexuality and race. The respected journal Science wrote in 1990: "To many in the scientific community, Watson has long been something of a wild man, and his colleagues tend to hold their collective breath whenever he veers from the script."
In 1997, he told a British newspaper that a woman should have the right to abort her unborn child if tests could determine it would be homosexual. He later insisted he was talking about a "hypothetical" choice which could never be applied. He has also suggested a link between skin colour and sex drive, positing the theory that black people have higher libidos, and argued in favour of genetic screening and engineering on the basis that " stupidity" could one day be cured. He has claimed that beauty could be genetically manufactured, saying: "People say it would be terrible if we made all girls pretty. I think it would great."

he shocked a scientific audience at the University of California at Berkeley by making unsupported assertions about the supposed biochemical links between sex and skin color, fat and ambition.
Watson's thesis is that a chemical called pom-C breaks down into derivative enzymes that influence a series of behaviors.
One of the pom-C derivatives is melanin, which darkens the skin. Watson described an experiment in which melanin was found to have a Viagralike effect.
He contrasted slides of bikini-clad women with veiled Muslim women to suggest that sunlight stimulated sexual desire. At another point, he described how another pom-C derivative influenced the fat cycle, and suggested that heavier people have less ambition than thin people.
"Whenever you interview fat people, you feel bad because you know you're not going to hire them," Watson said during a seminar on the UC Berkeley campus in October.
