Phylogenetic Origins of Brain Organisers
The regionalisation of the nervous system begins early in embryogenesis, concomitant with the establishment of the anteroposterior (AP) and dorsoventral (DV) body axes. The molecular mechanisms that drive axis induction appear to be conserved throughout the animal kingdom and may be phylogenetically older than the emergence of bilateral symmetry. As a result of this process, groups of patternin...
متن کاملPhylogenetic Origins of Antibody Structure
The anuran amphibian, Rana catesbiana, has been found to possess at least two kinds of immunoglobulins corresponding to gammaG- and gammaM-classes. These classes have the same chain structures as those of their counterparts in higher animal species. Light chains of both immunoglobulins had molecular weights of 20,000. Heavy chains of the gammaM-class had molecular weights of 72,100; those of th...
متن کاملDual phylogenetic origins of Nigerian lions (Panthera leo)
Lion fecal DNA extracts from four individuals each from Yankari Game Reserve and Kainji-Lake National Park (central northeast and west Nigeria, respectively) were Sanger-sequenced for the mitochondrial cytochrome b gene. The sequences were aligned against 61 lion reference sequences from other parts of Africa and India. The sequence data were analyzed further for the construction of phylogeneti...
متن کاملPhylogenetic Cascades and the Origins of Tropical Diversity
For organisms involved in specialized ecological interactions, the potential exists to have congruent evolutionary histories, such that diversification within one lineage of organisms parallels diversification within another. This model of shared evolutionary history has most often been explored in a bitrophic context, particularly with plants and specialized herbivorous insects, though also wi...
متن کاملOrigins of social parasitism: the importance of divergence ages in phylogenetic studies.
Phylogenetic studies on insect social parasites have found very close host-parasite relationships, and these have often been interpreted as providing evidence for sympatric speciation. However, such phylogenetic inferences are problematic because events occurring after the origin of parasitism, such as extinction, host switching and subsequent speciation, or an incomplete sampling of taxa, coul...
