“…As pointed out by Schaffer (1977), the analysis performed by Lawlor and Maynard Smith is identical to a method provided independently by Allen (1976). Similar approaches were also described by Case and Casten (1979), Case (1982), Case and Sidell (1983), Roughgarden et al (1983), andRoughgarden (1983b). Smith (1976).…”

a small group of investigators at the scientific research station at Abisko, Sweden, for the purpose of examining various conceptual and mathematical views of the evolution of complex systems. The stated theme of the meeting was deliberately kept vague, with only the purpose of discussing alternative mathematically based approaches to the modeling of evolving processes being given as a guideline to the participants. In order to limit the scope to some degree, it was decided to emphasize living rather than nonliving processes and to invite participants from a range of disciplinary specialities spanning the spectrum from pure and applied mathematics to geography and analytic philosophy.The results of the meeting were quite extraordinary; while there was no intent to focus the papers and discussion into predefined channels, an immediate self-organizing effect took place and the deliberations quickly oriented themselves into three main streams: conceptual and formal structures for characterizing system complexity; evolutionary processes in biology and ecology; the emergence of complexity through evolution in natural languages. The chapters presented in this volume are not the proceedings of the meeting. Following the meeting, the organizers felt that the ideas and spirit of the gathering should be preserved in some written form, so the participants were each requested to produce a chapter, explicating the views they presented at Abisko, written specifically for this volume. The results of this exercise form the volume you hold in your hand.Special thanks for their help in various phases of organizations of the meeting and arrangement of the publication of this volume are due to M. Olson, P. Sahlstrom, and R. Ouis. December 1985 John Casti, Vienna Anders Karlqvist, StockholmThe International Institute for Applied Analysis is a nongovernmental research institution, bringing together scientists from around the world to work on problems of common concern. Situated in Laxenburg, Austria, IIASA was founded in October 1972 by the academies of science and equivalent organizations of twelve countries. Its founders gave IIASA a unique position outside national, disciplinary, and institutional boundaries so that it might take the broadest possible view in pursuing its objectives:To promote international cooperation in solving problems arising from social, economic, technological, and environmental change To create a network of institutions in the national member organization countries and elsewhere for joint scientific research To develop and formalize systems analysis and the sciences contributing to it, and promote the use of analytical techniques needed to evaluate and address complex problems To inform policy advisors and decision makers about the potential application of the Institute's work to such problemsThe Institute now has national member organizations in the following countries: Complexity and the Evolution of Living SystemsOne of the most evident features distinguishing living from nonliving systems is the tende...

“…However, examination of other habitat variables might prove interesting. In particular, some Greater AntUlean derivatives (e.g., A. conspersus [Losos et al, 1993]) and Lesser AntUlean species (e.g., A. marmoratus, A. oculatus [Lazell, 1962[Lazell, , 1972Malhotra & Thorpe, 1991, 1994) use a wide variety of different habitat types (e.g., arid scrub, rainforest for the latter two species), whereas other species are more restricted in use of habitat types (Lazell, 1972;Roughgarden et al, 1983). Greater Antillean ecomorph species also vaiy in the breadth of habitat type use (e.g.…”

“…Suppose that there was some trait which would evolve by individual selection if variation for it existed, but which would increase the chance of the deme to go extinct (for example, the size variation in the smaller of the two competing species in Roughgarden's models (Roughgarden et al, 1983)). Now, suppose the variation between populations was for the rate of introduction of this phenotypic variant.…”

The opportunistic character of adaptation through natural selection can lead to 'evolutionary pathologies'-situations in which traits evolve that promote the extinction of the population. Such pathologies include imprudent predation and other forms of habitat over-exploitation or the 'tragedy of the commons', adaptation to temporally unreliable resources, cheating and other antisocial behavior, infectious pathogen carrier states, parthenogenesis, and cancer, an intra-organismal evolutionary pathology. It is known that hierarchical population dynamics can protect a population from invasion by pathological genes. Can it also alter the genotype so as to prevent the generation of such genes in the first place, i.e. suppress the evolvability of evolutionary pathologies? A model is constructed in which one locus controls the expression of the pathological trait, and a series of modifier loci exist which can prevent the expression of this trait. It is found that multiple 'evolvability checkpoint' genes can evolve to prevent the generation of variants that cause evolutionary pathologies. The consequences of this finding are discussed.
