Humans Haven't Stopped Evolving
Yet many scientists believed that, during the same time frame, human DNA hadn’t changed much. Using the largest collection of ancient human DNA samples ever compiled, paired with new statistical methods, Reich and his colleagues discovered that the human genome has actually evolved rapidly during the past 10,000 years. The study, published in Nature in April, showed hundreds of genetic shifts in 16,000 individuals who lived in modern-day Europe across an 18,000-year period.
