最近英国的科学家研究发现,那些早生孩子的母亲很可能寿命相对短。科学家以果蝇作为研究对象,将较早进行繁殖的雌性果蝇和较晚繁殖的果蝇进行比较,结果发现在繁殖后的30天后,产卵较早的果蝇“妈妈”的死亡率明显地比那些产卵晚的果蝇“妈妈”要高。在第40天,这种死亡率的差异达到最大,此后,这一差异逐渐变小。产卵较晚的果蝇妈妈们普遍地寿命长。 A recent British study by scientists found that mothers of those who were born early were likely to have relatively short lifespans. Scientists using fruit flies as a research object, the earlier breeding of female fruit flies and late breeding fruit flies were compared and found that 30 days after breeding, the earlier spawning fruit fly “mother” mortality was significantly It is higher than the “mother” of fruit flies that are late for spawning. On day 40, the difference in mortality reached its maximum, after which the difference became smaller. Drosophila moths who spawn later generally have long life expectancy.
