The fashion for having children later in life could lead to women becoming more fertile in their 40s and beyond, scientists have suggested.
科學家指出,現(xiàn)在的晚育趨勢將讓未來女性40歲以后的生育能力增強。
As many women wait until they are older to give birth, only those with longer lasting fertility genes will be successful.
許多女性會等到年齡很大時才生育,而只有那些帶有更持久的繁殖基因的女性才會成功晚育。
That means the average length of fertility will grow as their genes will be passed on to their children.
這意味著生育能力持續(xù)的平均時間會隨著她們的基因遺傳給下一代而變長。
