Research Abstract

Sexual difference is observed in various behaviors, including parental care, mating behavior, migration, and altruism. The purpose of the present collaborative study is to identify them over broad taxonomic categories, and to study the evolutionarily origin of sex expression both animals and plants, through comparative ecology and mathematical modelling studies. Ecologists studying primates, mammals, birds, fish, insectes, and plants together with theoreticians who are strongly interested in the origin of sexual difference are involved this enterprise.
Four meetings and an open lecture were held. There researchers studying vastly different subjects exchanged their views on the evolutionary problem of sex. We also invisted several lecturers from other field, including genetical mechanism of sex determination, or, the parthenogenesis, or the physiological mechanisms to behavioral sex determination in mammals.
In light of theoretical evolutionary ecology, the issues concering the sex include not only the behavioral differences between sexes, but also sex allocation (sex ratio, hermaphroditism versus separate sex, sex reversals, genetic versus environmental sex determination), and the most difficult problem of the evolution of sexual reproduction (mixis). It is obviously impossible to solve all these vast problems in the two years. Many achievements were made by each reserchers as explained in a report separately published. However the largest contribution of this research project is that we succeeded in identifying the issues common to different fields.
