The paper identifies a novel expression domain of extradenticle in harvestman patella, suggesting that modification of an ancient gene, not neofunctionalization of a new copy, underlies the origin of the chelicerate patella.

The paper describes the discovery of a new species of Paleoamblypygi and uses it to generate the first molecular phylogeny of whip spiders, showing the importance of relict taxa in divergence time estimation.
