Living species of daddy longlegs has two additional sets of underdeveloped eyes as embryos

While some people may first associate daddy longlegs with, well, their long legs, researchers Guilherme Gainett and Prashant Sharma have been especially focused on the arachnids' eyes. In their paper published last week in the journal Current Biology, the researchers found that a living species of daddy longlegs has two additional sets of underdeveloped eyes as embryos, implying that the species diversified earlier in the evolutionary tree than scientists believed.
