Claiming descent from convicts who were sent to Australia during the early period of British settlement is more than just about blood ties, it is also an aspect of national identity for many Australians. Analyses of nationally representative survey data show that younger, left-leaning, working class Australians are most likely to identify as convict descendants, while older, high income, educat...

The recurrent evolution of convergent forms is a widespread phenomenon in adaptive radiations (e.g., [1-9]). For example, similar ecotypes of anoles lizards have evolved on different islands of the Caribbean, benthic-limnetic species pairs of stickleback fish emerged repeatedly in postglacial lakes, equivalent sets of spider ecomorphs have arisen on Hawaiian islands, and a whole set of converge...

Determining the genetic bases of adaptations and their roles in speciation is a prominent issue in evolutionary biology. Cichlid fish species flocks are a prime example of recent rapid radiations, often associated with adaptive phenotypic divergence from a common ancestor within a short period of time. In several radiations of freshwater fishes, divergence in ecomorphological traits - including...

Sensory systems play crucial roles in survival and reproduction. Therefore, sensory plasticity has important evolutionary implications. In this study, we examined retinal plasticity in five species of cichlid fish from Lake Malawi. We compared the cone opsin expression profiles of wild-caught fish to lab-reared F(1) that had been raised in a UV minus, reduced intensity light environment. All of...

African Great Lake cichlid populations are divided into thousands of genetic subpopulations. The low gene flow between these subpopulations is thought to result from high degrees of natal philopatry, heavy predation pressure, and a patchy distribution of preferred habitats. While predation pressure and habitat distribution are fairly straightforward to assess, data on dispersal distances and ra...

Although the telencephalon of ray-finned fishes has garnered considerable attention from comparative neuroanatomists, detailed descriptions of telencephalic organization are available for only a few species. This necessarily limits our understanding of telencephalic evolution, particularly in light of the extraordinary diversity of ray-finned fishes. Thus, we have charted the cyctoarchitecture ...

Convict cichlids, indigenous to Central America, are a common study organisms in the fields of ethology, behavioral endocrinology, and evolutionary biology. A clear understanding of their behavior within their natural environment is critical to understanding the evolutionary history of this species. Convict cichlids are monogamous bi-parental fish which live in a world of enormous predation pre...

again somewhere and celebrate our traditional barbecue on the roof !!! Johannes set foot on the shores of the Great East African Lakes. Luckily, Darwin stumbled over some remote Islands in the Pacific Ocean instead and found some finches there, and later wrote his famous books. I think we are very lucky that we have something like an Evolutionary Theory today. For if Darwin had seen the splendi...
