[unable to retrieve full-text content]Two lineages of dangerous arachnids found in Australia -- long classified as distantly related in the official taxonomy -- are, in fact, relatively close evolutionary cousins. The lineages include the most venomous spiders in the world. The findings could help in the development of novel antivenoms, as well as point to...
