The following papers relate to research on evolution, cytogenetics and speciation that William Hall carried out at Southern Illinois University - Edwardsville, Harvard University and at the University of Melbourne (Australia) during the late 1960's and 1970's. After Dr Hall's graduation from Harvard, due to paradigmatic misunderstandings with reviewers of his draft papers and his inability to find a secure academic appointment that provided a practical situation for continuing his research program, some core material was either published obscurely or not at all. However, the body of this work is still relevant today and Hall introduces some interesting theoretical ideas in these works that have still not been adequately tested. Questions that might be asked are do the agamid and chameleontid radiations in Africa show similar patterns of speciation and chromosome variation to those observed in the iguanid and sceloporine lizards in North America? We are happy to make this work available to the public via the Web.
Dr Hall has scanned and converted the key papers to HTML, allowing the body of knowledge to be explored as a hypertext. Hotlinks below provide direct access to the respective papers.
For biographical notes on William Hall and his recent work in knowledge management, organizational theory and organizational evolution, see his personal web page: Evolutionary Biology of Species and Organizations. For those interested on the current state of research relating to sceloporine lizards, Jack Sites and his students and colleagues at Brigham Young University were able to extend the study of the genetic and chromosomal variation in the sceloporines well beyond where William Hall had to abandon the research. However, many questions remain unanswered as indicated in his recent paper, Delimiting species: a Renaissance issue in systematic biology, TRENDS in Ecology and Evolution Vol.18 No.9, p. 462 September 2003.
