The domain-independent and domain-dependent approach to the evolution of cognition have been taken by separate groups of researchers who have focused exclusively on either the formal properties or the distinct cognitive demands of tasks. We express the view that synthesizing the two approaches could lead to a more complete understanding, and…

First, I describe why intelligence (Spearman's "g") can only be fully understood through "r-K" theory, which places it into an evolutionary framework along with brain size, longevity, maturation speed, and several other life-history traits. The "r-K" formulation explains why IQ predicts longevity and also why the gap in mortality rates between…

Molecular genetics is a rapidly changing field with new developments almost from day to day. One interesting hypothesis that has come from everyone's ability to sequence proteins and/or genes is that of the molecular clock. This hypothesis postulates that homologous sequences of DNA and thus macro molecules evolve at a constant and invariable rate…

A comprehensive evolutionary framework for understanding the maintenance of heritable behavioral variation in humans is yet to be developed. Some evolutionary psychologists have argued that heritable variation will not be found in important, fitness-relevant characteristics because of the winnowing effect of natural selection. This article…

Comments on the article by J. S. Hyde (see record EJ733581), which reviewed the results of 46 meta-analyses of studies investigating gender differences and produced results that supported the gender similarities hypothesis that men and women are similar along most psychological traits. The current authors agree with the gender similarities…

In this article, the author shares some of the background material that did not make it into his biography of Charles Darwin, "The Tree of Life." Specifically, he discusses the important role that teachers played in Darwin's life, from his demanding father (Dr. Darwin) to zoologist Dr. Robert Grant and taxidermist John Edmonstone (a freed slave).

Phylogenetic trees, which are depictions of the inferred evolutionary relationships among a set of species, now permeate almost all branches of biology and are appearing in increasing numbers in biology textbooks. While few state standards explicitly require knowledge of phylogenetics, most require some knowledge of evolutionary biology, and many…

Teaching students to make connections between what they learn in the classroom and what they see in everyday life is imperative. As biology instructors, they may choose to teach biology devoid of social context, believing that students can make these connections on their own. However, students model their instructors' behaviors, and follow their…

This study took place during a First Year Seminar course where 20 incoming college freshmen studied the central topic of the nature of science within the context of biological evolution. The instructor researched students' understandings in the nature of science as they progressed through the course by examining a variety of qualitative and…

Derived changes in genes associated with primary microcephaly (MCPH) have been suggested to be "currently sweeping to fixation" i.e., increasing in frequency in most populations, with the likely outcome that the derived allele will completely displace the ancestral allele over time. Possible causes for this sweep include effects on human reasoning…

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…

"Approaches and Strategies in Next Generation Science Learning" examines the challenges involved in the development of modern curriculum models, teaching strategies, and assessments in science education in order to prepare future students in the 21st century economies. This comprehensive collection of research brings together science educators,…

The purpose of this article is to compare the teaching of religion in government-run primary and secondary educational institutions in Poland and Canada (Ontario and Quebec). The theoretical framework for this work is supplied by the general idea that the school is an organization and social institution. It is concluded that religious instruction…

Teaching the theory of evolution in classrooms takes place in a social, intellectual, and pedagogical context which must be considered with care if students are to receive a complete and authentic education. In addition to the science education literature on this topic, attention is directed to the expanding literature on science and religion, as…

This study examines the relationship between biology teachers' evolution teaching practices and their regard and use of Indiana state evolution standards. A survey developed by the authors contained five subscales: use of standards; attitude toward standards; attitude toward evolution standards; evolution teaching practices; and demographic…
