Natural selection has been acting on hundreds of human genes in the last 3,000 years

Natural selection, the evolutionary process that guides which traits become more common in a population, has been acting on us for the past 3,000 years, right up to the modern day, new research suggests. And it seems to be acting in surprising ways on complex traits encoded by multiple genes, such as those tied to intelligence, mental illness and even cancer. In natural selection, genes that confer some sort of survival or reproductive advantage get passed down and persist in a population, while those that lead to lower survival or fewer offspring become less common. There's no question that natural selection shaped the evolution of humans in our more distant past. But the impact of natural selection in the recent past is a much more controversial question.
