Phylogeny and divergence time of Neogastropoda in The Persian Gulf

Neogastropoda is one of Caenogastropoda’s orders belongs to Gastropoda class. There are some families of this clade in the Persian Gulf. The phelogeny and divergence time of them have been studied for the first in the northern rocky coastal zones of Persian Gulf during years 2013 and 2014. After morphological identifications of species, DNA extraction, amplifying partial of cytochrome oxidase COI and 16S rRNA and sequencing procedure were done in the laboratory. In this study 7 COI and 3 16S sequencing belonging to 4 species were measured. Also, phylogeny analyses with drawing phylogeny trees of Maximum Likelihood, Maximum Parsimonyand Bayesian were done using MEGA6, PAUPand BEAST softwares. Results showed that the members of Neogastropods in the Persian Gulf have been divergent in middle Eocene; So that their common ancestor astimatedin about 47 million years ago. In addition Neogastropoda is a monophyletic clade.
