on its head (when the Medieval rulers were thrown out and replaced by a more exact apparatus now called the state) when the human sciences suddenly discovered: "The set of mechanisms through which the basic biological features of the human species became an object of a political strategy and took on board the fundamental facts that humans were now a biological species." Sociobiology Sociobiology departs perhaps the furthest from classical social evolutionism. It was introduced by Edward Wilson in his 1975 book Sociobiology: The New Synthesis and followed his adaptation of evolutionary theory to the field of social sciences. Wilson pioneered the attempt to explain the evolutionary mechanics behind social behaviours such as altruism, aggression, and nurturance. In doing so, Wilson sparked one of the greatest scientific controversies of the 20th century by introducing and rejuvenating neo-Darwinian modes of thinking in many social sciences and the humanities, leading to reactions ranging from fundamental opposition, not only from social scientists and humanists but also from Darwinists who see it as “excessively simplistic in its approach”, to calls for a radical restructuring of the respective disciplines on an evolutionary basis. The current theory of evolution, the modern evolutionary synthesis (or neo-darwinism), explains that evolution of species occurs through a combination of Darwin's mechanism of natural selection and Gregor Mendel's theory of genetics as the basis for biological inheritance and mathematical population genetics. Essentially, the modern synthesis introduced the connection between two important discoveries; the units of evolution (genes) with the main mechanism of evolution (selection). Due to its close reliance on biology, sociobiology is often considered a branch of the biology, although it uses techniques from a plethora of sciences, including ethology, evolution, zoology, archaeology, population genetics, and many others. Within the study of human societies, sociobiology is closely related to the fields of human behavioral ecology and evolutionary psychology. Sociobiology has remained highly controversial as it contends genes explain specific human behaviours, although sociobiologists describe this role as a very complex and often unpredictable interaction between nature and nurture. The most notable critics of the view that genes play a direct role in human behaviour have been biologists Richard Lewontin Steven Rose and Stephen Jay Gould. Given the convergence of much of sociobiology's claims with right-wing politics, this approach has seen severe opposition both with regard to its research results as well as its basic tenets; this has led even Wilson
