In nature, competition within and between species is the norm, yet nature is also reputed to be a "peaceable kingdom" where animals cooperate rather than compete. This study explored how such contrasting views of nature influence students' biological reasoning. College undergraduates (n = 165) assessed the prevalence of cooperative…

The ability to understand the mental states of other individuals is central to human social behavior, yet some theory of mind capacities are shared with other species. Comparisons of theory of mind skills across humans and other primates can provide a critical test of the cognitive prerequisites necessary for different theory of mind skills to…

Cosmopolitanism is an ancient Greek notion which in modern times has found its way into educational practice. It expresses a moral responsibility toward everyone irrespective of cultural background, looks or ability. However, it is an ideology difficult to operationalise and convey in education if the objective is to change learners' attitudes for…

Darwin's theory of evolution is explicitly competitive, yet co-operation between individuals is a common phenomenon. The Prisoner's Dilemma model is central to the teaching of the evolution of co-operation. The best-known explorations of the Prisoner's Dilemma are the tournaments run by Robert Axelrod in the 1980s. Aimed at students of biological…

Francis Galton, Charles Darwin's cousin, had wide and varied interests. They ranged from exploration and travel writing to fingerprinting and the weather. After reading Darwin's "On the Origin of Species," Galton reached the conclusion that it should be possible to improve the human stock through selective breeding, as was the…

Are human beings intrinsically good but corruptible by the forces of evil, or the reverse, innately sinful yet redeemable by the forces of good? Are people built to pledge their lives to a group, even to the risk of death, or the opposite, built to place one's self and one's families above all else? Scientific evidence, a good part of it…

This exercise demonstrates the principle of parsimony in constructing cladograms. Although it is designed using mammalian cranial characters, the activity could be adapted for characters from any group of organisms. Students score categorical traits on skulls and record the data in a spreadsheet. Using the Mesquite software package, students…

Moral foundations theory (MFT) proposes the existence of innate psychological systems, which would have been subjected to selective forces over the course of evolution. One approach for evaluating MFT, therefore, is to consider the proposed psychological foundations in relation to the reconstructed Environment of Evolutionary Adaptedness. This…

This paper analyzes the debates on "interracial competition" and "racial extinction" in the biological discourse on human evolution during the second half of the nineteenth century. Our intention is to discuss the ideological function of these biological concepts as tools for the naturalization and scientific legitimation of racial hierarchies…

Evolutionary and biological approaches tend to suggest that social dominance is predominately an aspect of male social organization. Furthermore, when females behave non-normatively, they are less positively evaluated than males engaging in the same behavior. Alternate, less familiar models of females and dominance/aggression underlie the present…

It is widely believed that the end of Nazism, and the postwar era brought an end to academic theories and discourses regarding inherent racial inferiority. There was little tolerance Hawkins (1997) argues, for biological justifications for racism, war, and exploitation. The infamous Social Darwinism of key intellectual Herbert Spencer, and its…

Drawing on the theoretical and empirical foundations of two evolutionary models, we argue that, among humans and other mammals, a twofold selection process would parsimoniously account for sex-linked advantages in spatial contexts. In males, a superiority for both solving navigation-related spatial problems and understanding physical principles…

The Prisoner's Dilemma (PD) game demonstrates how cooperative or competitive choices influence decision making between two people or groups. A study of 48 college students tested an infinite-choice, continuous-time version of the PD. Results indicated that oscillatory cooperation was the predominant over-time behavior, that players matched…

Gene-culture interactions have largely been modelled employing population genetic-type models. Moreover, in the most notable application to date, the "interactive" modes have been one way rather than bidirectional. This paper suggests using game theoretic, fully interactive models. Employing the logic utilized in population ecology for coevolution…

Focuses on some apparently evolved features of human adolescence and their possible functions, including the pubertal growth spurt, sexual size dimorphism and bimaturism, the greater aggressiveness of males, heightened concern with one's social standing and the factors affecting it, intergenerational friction, same-sex aggregations and solidarity,…
