From The Daily Mail:
Yesterday, Dr Watson issued an apology.
"Science is no stranger to controversy and I am not one to shy away from tackling issues, however, difficult they might prove to be," he said.
"I have had my share of controversy, as many of you know. But I am mortified about what has happened.
"More importantly, I cannot understand how I could have said what I am quoted as having said. I can certainly understand why people, reading those words, have reacted in the ways they have.
"To all those who have drawn the inference from my words that Africa, as a continent, is somehow genetically inferior, I can only apologize unreservedly.
"That is not what I meant. More importantly from my point of view, there is no scientific basis for such a belief. "
