Diversification of hth2 expression during spider evolution. The drawings show a schematic summary of hth2 expression in the walking legs in four different spider species (Acanthoscurria geniculata after [24]). Black stripes indicate strong expression in the walking legs, light gray bars represent weak expression. The cladogram at the left shows the phylogenetic relationships between the species (phylogeny simplified after [64]). The black box indicates the spider specific duplication event of hth that resulted in the origin of hth2 at the base of the spider phylogenetic tree
