Novel functional specificity of HoxA-11 evolves through changes in the transcription factor protein
Meeting Abstract 20.2 Thursday, Jan. 3 Novel functional specificity of HoxA-11 evolves through changes in the transcription factor protein. LYNCH, Vincent/J*; WAGNER, Gunter/P; Yale University; Yale University vincent.j.lynch@yale.edu The evolution of morphological characters is mediated by the evolution of gene regulation. While there is broad agreement for the importance of cis-regulatory evolution, it has only recently been […]
Molecular Phylogenetic Evidence Clarifies Hydras Closest Relatives
Meeting Abstract 20.4 Thursday, Jan. 3 Molecular Phylogenetic Evidence Clarifies Hydra�s Closest Relatives NAWROCKI, A.M.; University of Kansas, Lawrence nawrocki@ku.edu Knowledge of the phylogenetic position of model organisms provides a comparative framework for investigating the evolution of development. Hydra has been a key model organism for the study of developmental pathways; however, further insight into the evolution […]

Why does genetic diversity of mitochondrial genes not reflect population size
Meeting Abstract 19.6 Thursday, Jan. 3 Why does genetic diversity of mitochondrial genes not reflect population size? KNOTT, K. E.; University of Jyvaskyla, Finland emily.knott@bytl.jyu.fi According to neutral theory, the amount of genetic variation within a population will be positively correlated with population size. However, according to a recent analysis by Bazin and colleagues (Science 312:570-572), mitochondrial […]
