Relaxed phylogenetics and dating with confidence plos biology
Ancestral state reconstructions revealed that the most recent common ancestor of extant stomatopods had eyes with six midband rows of hexagonal ommatidia.Hexagonal ommatidia are interpreted as plesiomorphic in stomatopods, and this is consistent with the malacostracan ground-plan.
A relaxed molecular clock, calibrated by seven fossil-based age constraints, was used to date the origin and major diversification events of stomatopods.Guinane CM, Zakour NLB, Tormo-Mas MA, Weinert LA, Lowder BV, Cartwright RA, Smyth DS, Smyth CJ, Lindsay J, Gould KA, Witney A, Hinds J, Bollback JP, Rambaut A, Penades J & Fitzgerald JR (2010) Genome Biology and Evolution 2, 454-466.Fraser C, Donnelly CA, Cauchemez S, Hanage WP, Van Kerkhove MD, Hollingsworth TD, Griffin J, Baggaley RF, Jenkins HE, Lyons EJ, Jombart T, Hinsley WR, Grassly NC, Balloux F, Ghani AC, Rambaut A & Ferguson NM (2009) Science 325, 1072 - 1073.

Our study provides insight into the evolutionary timescale and systematics of Stomatopoda, although further work is required to resolve with confidence the phylogenetic relationships among its superfamilies.
Stomatopoda is one of the most distinctive orders of Crustacea.
