Given the centrality of evolutionary theory to the study of biology, we present a strategy for reinforcing its importance by appropriately recontextualizing classic and well-known experiments that are not explicitly linked with evolution in conventional texts. This exercise gives students an appreciation of the applicability of the theory of…

This practical lesson describes how students in six eighth grade science classes participated in a lesson combining the National Core Arts Standards with the Next Generation Science Standards. The goal of the lesson was to provide visual representations of finch beak form and function so students could better understand genetic variation and how…

The contemporary fields of interdisciplinary studies and the policy sciences have evolved over similar intellectual paths and timelines, beginning in the early 20th century. Both have their roots in professional efforts--within and outside the academy--to address numerous, growing, and complex problems that face humanity. The policy sciences'…

Natural selection is one of the most important topics in biology and it helps to clarify the variety and complexity of organisms. However, students in almost every stage of education find it difficult to understand the mechanism of natural selection and they can develop misconceptions about it. This article provides an active model of natural…

For many years biologists supposed that one group of microorganisms, which they called archaebacteria, were an ancient and primitive type of bacteria. Following biochemical analysis of their RNA and other cell components, it soon became clear that their distinct features merited classification in a separate domain, the archea. From an evolutionary…

New phylogenomic tools have made it possible to construct a robust phylogenetic tree of mollusks. This tree can be used to teach important evolutionary principles.

Many young learners are fascinated with fossils, particularly charismatic forms such as dinosaurs and giant sharks. Fossils provide tangible, objective evidence of life that lived millions of years ago. They also provide a timescale of evolution not typically appreciated by young learners. Fossils and the science of paleontology can, therefore,…

Teachers are being challenged to engage students in ways that will elevate student interest and understanding of concepts in science and encourage students to gather evidence to support what we know about science. It is critical for teachers to have budget-friendly, supporting activities that are aligned with current educational standards, that…

Interactions between evolutionary psychologists and developmental systems theorists have been largely antagonistic. This is unfortunate because potential synergies between the two approaches remain unexplored. This article presents a method that may help to bridge the divide, and that has proven fruitful in biology: dynamic optimization. Dynamic…

A point mutation in the MC1R gene, a G-protein-coupled receptor, has been found that could have led to the formation of two subspecies of Solomon Island flycatcher from a single ancestral population. I discuss the many roles that G-protein-coupled receptors play in vertebrate physiology and how one particular point mutation can have enormous…

Students compare banding patterns on hominid chromosomes and see striking evidence of their common ancestry. To test this, human chromosome no. 2 is matched with two shorter chimpanzee chromosomes, leading to the hypothesis that human chromosome 2 resulted from the fusion of the two shorter chromosomes. Students test that hypothesis by looking for…

Group singing is a common feature of classroom-based music education, and has often been proposed to have benefits that extend beyond acquisition of music skills, primarily in academic achievement. However, potential social and emotional well-being benefits have been under-represented in these discussions. This article proposes that an…

Although some creationist objections to evolutionary biology are simplistic and thus are easily refuted, when more technical arguments become widespread it is important for science educators to explain the relevant science in a straightforward manner. An interesting case study is provided by misguided allegations about how cytochrome c data…

The phenomenon known as "essentialism"--the belief that all species have an essential form with variation being a form of accident of aberration from the essence of the species--is widespread and important because it is at odds with biological reality. The prospect of teaching children about inheritance and evolution would be undermined…

The molecular basis of evolution is an important concept to understand but one that students and teachers often find challenging. This article provides training and guidance for teachers on how to present molecular evolution concepts so that students will associate molecular changes with the evolution of form and function in organisms. Included…
