吃掉配偶的雌蛛其后代48%可以活过一个月,
Those born of females who had let their partners live, had only a 12% chance of survivingthat long.
而放生配偶的雌蛛的后代存活相同时间的只有12%。
That is a staggering differenceand certainly, in evolutionary terms, enough to driveself-sacrificial behaviour by males,
这个差距是巨大的当然,按照进化论原则,足以使雄蛛采取自我牺牲行为。
since a male would have to mate successfully another three times to match the benefit hegains by this one suicidal act.
因此,为获得这一次自杀行为带来的好处,它之前必须成功交配三次。
The reason a male is almost three times as likely to be eaten if he has mated with the femalein question than if he has not is thus probably that he wants to be eaten, for the good of hisposterity.
讨论中,如果与雌蛛交配成功,雄蛛被吃的概率几乎是未交配成功的雄蛛的三倍,其原因可能是为后代着想,它希望被吃。
Just what it is that a male meal gives, via the female s digestive system, to the hatchlingspiders, remains to be determined.
通过雌蛛的消化系统,雄蛛给予孵化蜘蛛的是什么?这还有待探索。
