Abstract:
Molecular biology has re-opened the debate on metazoan diversification, including the vexing question of the origin of the major body plans (phyla). In particular, sequence analyses of rRNA have reconfigured significantly metazoan phylogeny, while homeobox genes suggest there could be an underlying similarity of developmental instructions in nominally disparate phyla. Despite this dramatic progress I argue that this renaissance of activity is lop-sided, but can be redressed by palaeontological data, especially from the Cambrian and immediately preceding Vendian. The fossil record complements and amplifies the conclusions derived from molecular biology, notably in the early radiation of cnidarians (Ediacaran faunas) and key steps in the diversification of the protostomes.

Abstract:
Colour vision is known to have arisen only twice—once in Vertebrata and once within the Ecdysozoa, in Arthropoda. However, the evolutionary history of ecdysozoan vision is unclear. At the molecular level, visual pigments, composed of a chromophore and a protein belonging to the opsin family, have different spectral sensitivities and these mediate colour vision. At the morphological level, ecdysozoan vision is conveyed by eyes of variable levels of complexity; from the simple ocelli observed in the velvet worms (phylum Onychophora) to the marvellously complex eyes of insects, spiders, and crustaceans. Here, we explore the evolution of ecdysozoan vision at both the molecular and morphological level; combining analysis of a large-scale opsin dataset that includes previously unknown ecdysozoan opsins with morphological analyses of key Cambrian fossils with preserved eye structures. We found that while several non-arthropod ecdysozoan lineages have multiple opsins, arthropod multi-opsin vision evolved through a series of gene duplications that were fixed in a period of 35–71 million years (Ma) along the stem arthropod lineage. Our integrative study of the fossil and molecular record of vision indicates that fossils with more complex eyes were likely to have possessed a larger complement of opsin genes.

Abstract:
Das tropische Südostasien, und besonders der Indo-Australische Archipel, ist bekannt für seine bemerkenswerte floristische und faunistische Diversität, besonders konzentriert in vier der identifizierten Biodiversitäts-Hotspots (Indochina, Sundaland, die Philippinen und Wallacea). In dieser Arbeit wird die biogeographische Geschichte Südostasiens beleuchtet, um Regionen mit einer erhöhten Biodiversität zu identifizieren und zu testen, ob dies mit Diversifikationen innerhalb der Region und Einwanderungen und/oder Auswanderungen korreliert und ob sich diese Faktoren über die Zeit hinweg ausgleichen. Ein besonderer Augenmerk wird auf Sulawesi und seine besondere Fauna gelegt, um zu testen, ob ein Ursprung durch Vikarianz für verschiedene Tiergruppen plausibel erscheint und wann Diversifikationen innerhalb der Fisch- und Schnecken-Radiationen im Malili-Seensystem begannen. Dabei wird auf Meta-Analysen und mehrere Disziplinen zurückgegriffen für eine integrative biogeographische Geschichte Südoastasiens und seiner Fauna, indem molekulare Uhr-Analysen, Berechnungen zur Ermittlung des Ursprungsortes mit tektonischen, paläogeographischen und klimatischen Rekonstruktionen verbunden werden, um potentielle Ursachen für die heutige Verbreitung zu finden.
Tropical Southeast Asia, and particularly the Indo-Australian Archipelago, is known for its tremendous floral and faunal biodiversity, mainly accumulated in four of the world’s biodiversity hotspots identified (Indochina, Sundaland, the Philippines, and Wallacea). Here, Southeast Asia’s biogeographic history is examined to identify areas being characterized by high levels of biodiversity (number of lineages, species richness) through time and to test whether the respective biota is mainly due to in situ diversification, immigration and/or emigration, or equilibrium dynamics. Moreover, this thesis focuses particularly on Sulawesi and its peculiar fauna to test if a vicariant origin appears plausible for certain groups and when the remarkable fish and snail radiations found in the Malili Lakes system started to diversify. To achieve this, meta-analytical and multi-disciplinary approaches are considered for an integrative historical biogeographic history of Southeast Asia and its biota by using molecular clock analyses and ancestral area estimations together with tectonic, palaeogeographic and climatic reconstructions to reveal potential causes for present-day distribution.

Abstract:
Snakes comprise nearly 4,000 extant species found on all major continents except Antarctica. Morphologically and ecologically diverse, they include burrowing, arboreal, and marine forms, feeding on prey ranging from insects to large mammals. Snakes are strikingly different from their closest lizard relatives, and their origins and early diversification have long challenged and enthused evolutionary biologists. The origin and early evolution of snakes is a broad, interdisciplinary topic for which experts in palaeontology, ecology, physiology, embryology, phylogenetics, and molecular biology have made important contributions. The last 25 years has seen a surge of interest, resulting partly from new fossil material, but also from new techniques in molecular and systematic biology. This volume summarises and discusses the state of our knowledge, approaches, data, and ongoing debates. It provides reviews, syntheses, new data and perspectives on a wide range of topics relevant to students and researchers in evolutionary biology, neontology, and palaeontology.

Abstract:
No field of science has cast more light on both the past and the future of our species than evolutionary biology. Recently, the pace of new discoveries about how we have evolved has increased (Culotta and Pennisi, 2005). It is now clear that we are less unique than we used to think. Genetic and palaeontological evidence is now accumulating that hominids with a high level of intelligence, tool-making ability, and probably communication skills have evolved independently more than once. They evolved in Africa (our own ancestors), in Europe (the ancestors of the Neanderthals) and in Southeast Asia (the remarkable ‘hobbits’, who may be miniaturized and highly acculturated Homo erectus). It is also becoming clear that the genes that contribute to the characteristics of our species can be found and that the histories of these genes can be understood. Comparisons of entire genomes have shown that genes involved in brain function have evolved more quickly in hominids than in more distantly related primates. The genetic differences among human groups can now be investigated. Characters that we tend to think of as extremely important markers enabling us to distinguish among different human groups now turn out to be understandable at the genetic level, and their genetic history can be traced. Recently a single allelic difference between Europeans and Africans has been found (Lamason et al., 2005). This functional allelic difference accounts for about a third of the differences in skin pigmentation in these groups. Skin colour differences, in spite of the great importance they have assumed in human societies, are the result of natural selection acting on a small number of genes that are likely to have no effects beyond their influence on skin colour itself. How do these and other recent findings from fields ranging from palaeontology to molecular biology fit into present-day evolution theory, and what light do they cast on how our species is likely to evolve in the future? I will introduce this question by examining briefly how evolutionary change takes place.
