However, phylogenetic analyses of the spidroin gene family indicate a minimum of three paralogs present in the common ancestor of Mygalomorphae and Araneomorphae (Starrett et al. 2012), suggesting paralogs deriving from the ancient duplication event may have created early duplicates in the spidroin gene family.
