Brandis1 1Christian-Albrechts-Universität zu Kiel, Zoological Museum, Kiel, Germany The Zoological Institute of Kiel University traces its origins to 1775, when the Danish entomologist Johann Christian Fabricius became the first Professor for Natural Sciences, Economy and Cameral Sciences in Kiel. This coincided with the opening of the Zoological Museum, where Fabricus founded the zoological collection in Kiel and started the modern entomological research in describing more than 9000 insect species and developing new classification concepts for insects. In the 19th century the zoological research expanded to many fields as anatomy, ecology, systematics and evolutionary research. One major focus became the marine science. Since the appointment of Karl August Moebius as the first “real” professor for Zoology in 1868, members of the Institute have been responsible for some major advances in marine zoology, as well as the realization of many of today’s prominent marine expeditions. For example, it was in this Institute that Karl August Moebius discovered the principles of biological interactions defining the term “Biocenosis”. Viktor Hensen coined the term “Plankton” and started a revolutionary research on this field. Adolf Remane discovered one of the last unknown habitats, the Mesopsammon and defined the criteria of homology. Famous expeditions with a strong participation of Kiel zoologists were the Plankton Expedition (1899), the German Deep Sea Expedition (1898-1899) or the German South Polar Expedition (1901-1903). KEY NOTE Darwin’s blind spot: the microbial making of a species *S. Bordenstein1 1Vanderbilt University, Departments of Biological Sciences and Pathology, Microbiology, & Immunology, Nashville, TN, USA Unprecedented attention to our microbial world has in part turned the fields of zoology and botany inward—toward a new awareness and understanding of the universality and complexity of host- microbiota relationships. Here, I present our laboratory's work on the origin of animal species in light of this conceptual shift. Specifically, we ask how do closely related host species vary in their bacterial symbiont communities? Does host evolutionary history affect microbiota differences between species? And what is the role of the microbiota in reproductive isolation and animal speciation? Overall, answers to these questions indicate that the composition and functional effects of an animal's microbial community can be closely allied with host evolution, even across wide-ranging timescales and in diverse animal systems reared under controlled conditions. Appreciation of the microbiota's role in animal speciation will provide a better understanding of what Darwin dubbed the "mystery of mysteries" in The Origin of Species. 3 Abstracts DZG Meeting 2016 109th ANNUAL MEETING of the GERMAN ZOOLOGICAL SOCIETY Deutsche Zoologische Gesellschaft PLENARY TALKS Science along the stem: New perspectives from deep time on the origin and early evolution of phenotypes * G. S. Bever1 1Johns Hopkins University School of Medicine, Center for Functional Anatomy & Evolution, Baltimore, MD, USA Evolutionary theory predicts that transformations in phenotypic characters involve a period of ancestral polymorphism wherein the probability of either the primitive or derived condition being expressed is relatively high. The periods of high variability circumscribed by changes in developmental potential may be extremely restricted in both time and space, especially when selection is strong, and may even be limited to a single ancestral population. In such cases, the probability of sampling fossils from within one of these “zones of variability” is so low that the resultant variation is unlikely to directly influence broad patterns of evolutionary change as communicated on a taxonomically inclusive tree. If, however, an evolving developmental network maintains its potential for high phenotypic variation over a significant period of geological time then the probability of sampling fossils from within this zone increases, as does its potential influence on our perception of evolutionary history. The hypothesis that extended zones of variability exist often enough to significantly affect our macroevolutionary view of the fossil record makes certain testable predictions. First, if the potential to express variation is controlled in part by phylogenetically informative transformations in the upstream architecture of the involved developmental pathways than polymorphism levels, when examined across a clade of extant species, should have phylogenetic structure. Second, characters more recently evolved and thus diagnostic of more exclusive clades should express higher levels of polymorphism within extant species than characters that evolved at deeper positions on the tree.
