   How many eyes does Phalangium opilio have?

   • Two sets of vestigial eyes shed light on the arachnids’ evolutionary history Despite its two-eyed appearance, Phalangium opilio has six peepers. The four extra eyes — leftovers of evolution — shed light on the evolutionary history of daddy longlegs. A species of daddy longlegs has been hiding four extra eyes.

   Does Phalangium opilio have WGD?

   • We assembled the first harvestman draft genome for the species Phalangium opilio, which bears elongate, prehensile appendages, made possible by numerous distal articles called tarsomeres. Here, we show that the genome of P. opilio exhibits a single Hox cluster and no evidence of WGD.

   What is Phalangium opilio?

   • Phalangium opilio is a univoltine species in Europe, producing one generation per year that overwinters as eggs. Two or more generations may occur within a year in some areas of North America, in which case eggs, immatures, and adults may all overwinter.

   Does Phalangium opilio have systemic genome duplication?

   • Developmental transcriptomes of the emerging model species Phalangium opilio have suggested that harvestmen do not exhibit systemic genome duplication, as evidenced by the absence of paralogy across the homeobox gene family [2, 14] and gene expression patterns of genes with known paralogues in arachnopulmonates [2, 6].
