  1. Phylogenetics of Cyprinodontiformes J.Ryce Martin

  2. Introduction • Pre 1981, Cyprinodontiformes (order of killifishes) classified by viparity • Now combination of morphological and molecular data are used to calculate relatedness • I used sequence alignment of the cytochromeb gene to construct a strict consensus parsimony tree, bootstrap values for the parsimony tree, and a distance neighbor-joining tree

  3. Fundulidae Rivulidae Aplocheilidae Poecilidae Goodeidae Profundulidae Cyprinodontidae Anablepidae

  5. Conclusions • Parsimony and Neighbor-Joining did not match up well • Could be due to different methods used • Bootstrap values appeared pretty good • Many branches collapsed creating polytomies • Hard polytomy • Family tree doesn’t match up well to literature
