Genetic diversity was found to be lowest in the Americas, which are widely
believed to be the last continents settled by humans.
The team concludes that perhaps 75 percent of humankind's modern genetic
variation is the result of random genetic drift.
The researchers suggest that only 25 percent of our genetic diversity stems
from the evolutionary process of natural selection-though such a number is
still significant.
"Undoubtedly natural selection has played an important role in altering our
genome during this migration out of Africa," Ramachandran said. "But it is
kind of new to think that genetic drift might have been responsible for this
much of human genetic variation."

Well there you go, a conclusion based on what you need to prove.
