Assessing the root of bilaterian animals with scalable phylogenomic methodsAndreas Hejnol
Kewalo Marine Laboratory, University of Hawaii, 41 Ahui Street, Honolulu, HI 96813, USA
Proc Biol Sci 276:4261-70. 2009..The work highlights the implications that these arrangements have for metazoan evolution and permits a clearer picture of ancestral morphologies and life histories in the deep past...
Acoel development indicates the independent evolution of the bilaterian mouth and anusAndreas Hejnol
Kewalo Marine Laboratory, PBRC, University of Hawaii, 41 Ahui Street, Honolulu, Hawaii 96813, USA
Nature 456:382-6. 2008..These results contradict the hypothesis that the bilaterian mouth and anus evolved simultaneously from a common blastoporal opening, and suggest that a through gut might have evolved independently in different animal lineages...
Coordinated spatial and temporal expression of Hox genes during embryogenesis in the acoel Convolutriloba longifissuraAndreas Hejnol
Kewalo Marine Laboratory, PBRC, University of Hawaii, 41 Ahui Street, Honolulu, HI 96813, USA
BMC Biol 7:65. 2009..As acoels appear to represent the sister group to the remaining Bilateria (Nephrozoa), investigating Hox gene expression will provide an insight into the ancestral features of the Hox genes in metazoan evolution...
Broad phylogenomic sampling improves resolution of the animal tree of lifeCasey W Dunn
Kewalo Marine Laboratory, PBRC, University of Hawaii, 41 Ahui Street, Honolulu, Hawaii 96813, USA
Nature 452:745-9. 2008..Many relationships between a stable subset of taxa find strong support, and a diminishing number of lineages remain recalcitrant to placement on the tree...
A developmental perspective: changes in the position of the blastopore during bilaterian evolutionMark Q Martindale
Kewalo Marine Laboratory, PBRC, University of Hawaii, 41 Ahui Street, Honolulu, HI, 96813, USA
Dev Cell 17:162-74. 2009....
Acoel development supports a simple planula-like urbilaterianAndreas Hejnol
Kewalo Marine Laboratory, Pacific Bioscience Research Center, University of Hawaii, Honolulu, HI 96813, USA
Philos Trans R Soc Lond B Biol Sci 363:1493-501. 2008..We also identify the developmental changes related to gastrulation that gave rise to the urbilaterian from a simpler cnidarian-like ancestor...
Homology of ciliary bands in Spiralian TrochophoresJonathan Q Henry
University of Illinois, Urbana, IL, 601 S Goodwin, Avenue Urbana, IL 61801, USA University of Hawaii, Kewalo Marine Laboratory, 41 Ahui Street, Honolulu HI 96813, USA
Integr Comp Biol 47:865-71. 2007..These findings have important implications for the interpretation of various hypotheses related to the evolution of metazoan phyla...
Ciliary photoreceptors in the cerebral eyes of a protostome larvaYale J Passamaneck
Kewalo Marine Laboratory, Pacific Biosciences Research Center, University of Hawaii, 41 Ahui Street, Honolulu, HI 96813, USA
Evodevo 2:6. 2011..abstract:..
Gene expression in bryozoan larvae suggest a fundamental importance of pre-patterned blastemic cells in the bryozoan life-cycleJudith Fuchs
Kewalo Marine Laboratory, Pacific Biosciences Research Center, University of Hawaii, 41 Ahui Street, Honolulu, HI 96813, USA
Evodevo 2:13. 2011..abstract:..
High-resolution fate map of the snail Crepidula fornicata: the origins of ciliary bands, nervous system, and muscular elementsAndreas Hejnol
University of Hawaii, Kewalo Marine Laboratory, 41 Ahui Street, Honolulu, HI 96813, USA
Dev Biol 305:63-76. 2007..Our study shows that both first and second velar ciliary bands are generated by the same cells that form the prototroch in other spiralians and apparently bear no homology to the metatroch found in annelids...
