Recently developed statistical tools have finally made this possible. With more sophisticated methods, my colleagues and I were reliably able to distinguish genetic changes, and thus to demonstrate an evolutionary shift toward a younger age at first birth in a small, insular population in Québec over the last 140 years.
最新研发的统计工具终于让实现这一目标成为可能。我和我的同事们利用更复杂的方法准确地分辨出基因的变化，从而证明了过去140年在魁北克的小部分孤立人群中出现了朝向初产年龄较低者的进化转移。
