The Evolution of Evolutionary Thinking in Chile

The scientific study of evolution in Chile has experienced periods of diversification and stasis, depending upon the social and political context at different times. In the eighteenth century, most of the natural history research consisted of systematics and taxonomy and, as in most of South America, this task was performed mainly by natural historian theologists. Later, the immigration of European scientists to Chile after independence from Spain in 1810 improved substantially its knowledge of the local biota and stimulated the diversification of naturalists in the country. Research in modern biology and the teaching of genetics in Chile can be traced back to Giovanni Noe, an Italian zoologist who had a profound impact in the first third of the twentieth century. In the 1960s–70s, Danko Brncic, a population geneticist educated in the tradition of Dobzhansky and the modern synthesis, led the most important diversification process in the study of evolutionary biology in the country. However, the military coup in 1973 brought this radiation to a sudden stop and produced a stasis period associated with the subsequent 17-year dictatorship. Evolutionary biology recovered its status after the re-establishment of democracy, and it is currently experiencing an exciting and renewed diversification period that has led to the foundation of the Chilean Society of Evolutionary Biology, the only scientific society for the study of evolution in Latin America. One of the missions of the Society is to bridge the gap between scientists and science educators in order to improve the teaching of evolution at different levels both in secular and religious schools. Even though the Roman Catholic Church has been a pivotal institution in the development of Chilean society, debate on evolutionism—creationism issues has been largely absent both in public and academic discussions. The influence of religion on science education has been sporadic, and mostly related to omission rather than tergiversation of scientific information in biology textbooks. Currently, schools are obliged by law to teach the basics of evolution in K-12 and K-16 levels (or their local equivalents). Because of this, there is little at present that suggests an organized creationist or intelligent design movement surge in the near future. Nevertheless, the high percentage of religiosity in Chile, together with the observation that the moral values of Chilean society are among the most conservative in the world, provide good reasons to remain vigilant.
