This lecture introduces students to the study of psychology from an evolutionary perspective, the idea that like the body, natural selection has shaped the development of the human mind. Prominent arguments for and against the theory of natural selection and its relationship to human psychology are reviewed. Students will hear several examples of how studying mental phenomenon from an evolutionary perspective can help constrain theories in...more

Environmental Politics and Law (EVST 255) The lecture charts the evolution of pesticide regulation in the United States. The evolution of the management and regulation of pesticides reflects changes in scientific understanding of pesticides as well as changes in human values. As technology allowed for testing of pesticides at smaller and smaller concentrations, restrictions on pesticide use grew. The government's growing understanding o...more

Neutral evolution occurs when genes do not experience natural selection because they have no effect on reproductive success. Neutrality arises when mutations in an organism's genotype cause no change in its phenotype, or when changes in the genotype bring about changes in the phenotype that do not affect reproductive success. Because neutral genes do not change in any particular direction over time and simply "drift," thanks in part to the...more

Government and Entrepreneurship: The Evolution of Entrepreneurship in China
Stanford / Entrepreneurship
Tarun Khanna, Professor at Harvard Business School, argues that the old equation that government = inefficient does not hold unilaterally but depends on the context. To illustrate, Khanna describes the evolution of the Communist Party of China and its efforts to co-opt entrepreneurs so that now the government and entrepreneurship is very closely integrated. In contrast, Khanna suggests that in India entrepreneurs keep their distance from t...more

Evolution plays an important though underutilized role in medicine. Evolution guides how our bodies respond to various treatments, how pathogens will respond to treatments, and how pathogens' responses will change over time. Pathogens oftentimes will evolve to an intermediate level of virulence where they become strong enough to infect a host and reproduce, but not so strong as to kill the host before it can spread the pathogen.

A revolution in technology can occur very quickly, says Wirt. The new product can rapidly displace the old. However, the evolution of a technology takes time. The potential impact of a technology is not often realized until much later.

There are several explanations for the evolution of sex and its continued prevalence. One is facilitating the spread of helpful mutations while hastening the removal of harmful ones. Another is expediting resistance against pathogens. Sex does have several costs compared to asex, such as only giving half your genome to offspring, having to find mates, and the risk of predation and STDs. Overall, the benefits outweigh the costs and sex has ...more

The history of life and evolution has been characterized by several key events. These events can be grouped as new hierarchal levels of selection coming into play, as biological units coming together in symbiosis and specialization, or in a number of other ways. Other important events are situations of conflict resolution or information transmission, from the genetic to the cultural level.
