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…

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…

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…

Faithful Christian engagement in education means both being at home and at odds with dominant culture. This stance of critical participation should produce an unbearable tension: can one both live in solidarity and dissent? Yet this unbearable tension is often not present in Christian experience--why? This article suggests four reasons: the…

The culture of modern science continues to establish its public identity by appealing to values and historical conceptions that reflect its appropriation of various religious ideals during its formative period, most especially in the rhetoric of Francis Bacon. These elements have persisted because they continue to achieve similar goals, but the…

Summarizes the Arkansas Creation Trial, which found the law requiring teachers to give balanced treatment to evolutionary ideas and creation science unconstitutional. A Canadian who was a witness at the trial expresses his concern regarding the threat of creationism in Canada and gives three reasons why Canadians must oppose creationism. (RM)

State standards for academic content vary enormously in how well they cover the topic of evolution, with many of those documents either ignoring or giving scant treatment to the core principles of that established scientific theory. This article presents the analysis of Education Week on state's standards treatment of evolution. Nearly all the…

The amount of dissolved oxygen in the oceans in the mid-Proterozoic period has evolutionary implications since essential trace metals are redox sensitive. The findings suggest that there is global lack of oxygen in seawater.

General intelligence (g) poses a problem for evolutionary psychology's modular view of the human brain. The author advances a new evolutionary psychological theory of the evolution of general intelligence and argues that general intelligence evolved as a domain-specific adaptation for the originally limited sphere of evolutionary novelty in the…

Developmentalism and Romanticism represent contrary poles in an absolutist dichotomy that frames most Western discourse on childhood. This opposition is generally recognized in current childhood studies but the former discourse still dominates institutional practices. Both views, however, rely on similar presumptions--that development is a linear…
