This article proposes that a complete account of cognitive evolution may have to accommodate a domain-general source of variance in mental abilities accounting for differences among primate taxa. Deaner, van Schaik, and Johnson [Deaner, R.O., van Schaik, C.P. and Johnson, V.E. (2006). Do some taxa have better domain-general cognition than others?…

Although molecular clock theory is a commonly discussed facet of evolutionary biology, undergraduates are rarely presented with the underlying information of how this theory is examined relative to empirical data. Here a simple contextual exercise is presented that not only provides insight into molecular clocks, but is also a useful exercise for…

Science education currently has incomplete understandings of potential relationships between students' beliefs in Nature of Science (NOS) and evolution, and how these beliefs may be related to scientific understandings of evolution. Because of evolution's prominence in science education, curricula decisions, and the future of science teaching and…

Science education controversies typically prove more intractable than those in scientific research because they involve a wider range of considerations (e.g., epistemic, social, ethical, political, and religious). How can educators acknowledge central issues in a controversy (such as evolution)? How can such problems be addressed in a way that is…

As part of the continuing series of the Reviewing Policy section, this article examines some of the recent literature on the creation-evolution controversy. These controversies are placed within a larger analysis of the growth of authoritarian populist movements in the United States. The article then focuses attention on debates both over a number…

Experiential learning can be an effective way to teach many concepts, and evolution is no exception. We describe the pedagogical techniques, class structure and learning objectives, travel logistics, and impact of three undergraduate honors-level experiential learning seminars that combined teaching topics related to evolution with a field trip to…

Educators are increasingly looking to Information and Communications Technology (ICT) as a means of enhancing student learning. The New Life Sciences (NLS) is a domain where complex and often abstract concepts must be communicated from a scientific perspective and understood by the student in terms of their underlying implications. This…

When students make the transition from one curriculum to another, with significant overlap of content, the challenge is not so much to impart new information but rather to tap into students' existing knowledge base. The purpose of this study was to determine if achievement in an external examination that requires analysis could be enhanced by the…

Historians of science have pointed to essentialist beliefs about species as major impediments to the discovery of natural selection. The present study investigated whether such beliefs are impediments to learning this concept as well. Participants (43 children aged 4-9 and 34 adults) were asked to judge the variability of various behavioral and…

Evolutionary processes can be studied in nature and in the laboratory, but time and financial constraints result in few opportunities for undergraduate and high school students to explore the agents of genetic change in populations. One alternative to time consuming and expensive teaching laboratories is the use of computer simulations. We…

The correlation between ontogeny and phylogeny is analyzed through the discussion of four theories on the reality, history, epigenetic, and ecological aspects of the mechanism of evolution. Also discussed are historical and creative aspects of evolution and three epigenetic mechanisms instantiated in the case of the amphibian embryo. (Author/RH)

Suggests a resolution to the apparent conflict between the Freudian and humanistic/transpersonal views of human nature. Presents a model which allows for the fulfillment of Freud's desire to account for both the life and death instincts as manifestations of a tendency to restore an earlier state of things. (LLL)

Life, as it has evolved over thousands of years, is a fantastic miracle. Since 1945 humans have built nuclear weapons so effectively that the release of them now would eradicate human life several times over. This annihilation potential makes life seem precious. Hard questions which must be asked are listed. (RM)

Doubts that random mutation provides sufficient variability for natural selection of complex biochemical processes; perhaps mutation is non-random? (AL)

Considers natural and cultural environmental factors likely to have been responsible for reduction in size of hominid teeth and simplification of their morphology during the Pleistocene. Cites fossil evidence and postulates selective mechanisms. (EB)
