   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.

   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 ].
