They found that some orb weavers-- web making spiders--are more genetically similar to webless spiders than the rest of the orb-weaving group.

他们发现，一些圆织蜘蛛——结网蜘蛛——与其他圆织蜘蛛相比，在基因上更类似于无网蜘蛛。

A later study comparing 3400 active genes in 70 species indicated that webless, ground-dwelling spiders, such as jumping spiders diversified much faster than the web weavers.

后来的一项研究比较了 70 个物种的 3400 个活性基因，表明无网的地栖蜘蛛，例如跳蛛，其多样性比织网蜘蛛快得多。
