Most animals have male and female sexes, implying that sex is ancient and beneficial; yet some have survived for millions of years without sex. The genome of the parthenogenetic nematode Diploscapter pachys gives clues as to how 'ancient asexual' animals can exist.
大多数动物都有雄性和雌性性别，这意味着性别是古老而有益的；然而，有些动物已经在没有性别的情况下存活了数百万年。孤雌生殖线虫 Diploscapter pachys 的基因组为我们提供了线索，说明“古老的无性”动物是如何存在的。
