Plant awareness disparity (PAD, formerly plant blindness) is the tendency not to notice plants in one's environment, which leads to the perspective that plants are unimportant. In this paper, we explore how plants and animals are represented in introductory biology textbooks to determine if these texts are contributing to PAD in undergraduate…

The teaching process is well described as an interaction between teacher, student, and content. Thus, it seems obvious that teachers must know the content to help students to learn it. Instruments have been developed to measure teachers' content knowledge (CK) in biology, but few of them have been provided to the scientific community. Furthermore,…

This article analyzes the power of ambiguous metaphors to present scientific novelty. Its focus is a series of papers by the prominent population biologist W. D. Hamilton in which he redefined the meaning of biological altruism. In particular, the article draws on Kenneth Burke's dramatistic pentad to examine why suggestions of motive are so…

Focuses on the way learning about genetics and evolution raises ideas that pupils and adults should relate to themselves whether what is learned helps reveal what science can and cannot say about human nature. Reviews the impact of informal learning after exploring the role and influence of informal learning channels. (Contains 79 references.)…

When the findings of sociobiology and ethology are properly interpreted, they are surprisingly compatible with commonsense ethical values, adding to our understanding of moral and ethical principles as an essential element of human social behavior. This paper provides a brief overview of the broader scientific interpretation to illustrate this…

Reviews current research on a woman's chances of bearing twins and the genetic relationship, prenatal competition, and personality similarities between twins. In addition, the nature/nurture controversy is discussed in terms of evidence from studies of identical twins reared apart. Future studies are suggested to discover the ways twinning might…

This brief paper suggests that Attention Deficit Disorder (ADD) may result from a specific "novelty seeking" gene which has been associated over the history of man's evolution with a biological advantage in situations where energy, risk taking, and creativity are essentials. It reviews research on the genetics of ADD which suggest that novelty…

Argues that an evolutionary perspective can unite the study of species-typical development and individual variation. Provides examples from the domains of personality, social, and intellectual development. Maintains that understanding the ways in which genes and environments work together helps developmentalists identify children who need…
