Meeting Abstract 11.3  Jan. 4  Rainbow Trout Possess Two Proinsulin-Encoding mRNAs that are Differentially Expressed CARUSO*, M.A.*; SHERIDAN, M.A.; North Dakota State Univ., Fargo Michael.Caruso@ndsu.edu Insulin plays an important role in the growth, development, and metabolism of vertebrates. Growing evidence suggests that some species of vertebrates possess two insulin genes; however, the phylogenetic distribution and the physiological […]

Meeting Abstract 10.5  Jan. 4  The evolution of Bilateria � insight from an acoel flatworm HEJNOL, A.*; MARTINDALE, M.Q.; Univ. of Hawaii, Honolulu; Univ. of Hawaii, Honolulu hejnol@hawaii.edu Recent molecular phylogenies place the Acoelomorpha (Acoela + Nemertodermatida) as the sister to all remaining Bilateria before their split into Proto- and Deuterostomes. This phylogenetic position makes the acoel […]

Meeting Abstract 10.2  Jan. 4  The elementary (pre-)nervous system reconsidered: new evidence from poriferans NICKEL, M; Stuttgart University, Germany michael.nickel@bio.uni-stuttgart.de In 1919 Parker presented basic ideas on the elementary nervous system. He assumed it became manifest due to the evolutionary pressure to coordinate independent effectors. The concepts behind his theory continued to hold with little changes over […]
