An overlooked feature of Darwin's work is his use of ““imaginary illustrations”” to show that natural selection is competent to produce adaptive, evolutionary change. When set in the context of Darwin's methodology, these thought experiments provide a novel way to teach natural selection and the nature of science.

Charles Darwin would be pleased to know that elementary school children in states that have adopted the Next Generation Science Standards (NGSS) are expected to demonstrate their understanding of several core evolutionary concepts, including trait variation and inheritance, fossils and extinct organisms, common ancestry, natural selection, and adaptation. However, he might also wonder how this is accomplished in the demanding 21st-century science curriculum. In files linked to this article, we provide four lesson plans – with engaging examples, natural selection games, and other interactive activities – that were designed to cover the NGSS Disciplinary Core Ideas in evolutionary biology for grades 3–5, in two one-hour lessons. The lesson plans were developed by college students under the guidance of evolutionary biologists and in consultation with elementary school teachers, and then field tested in elementary school classrooms, as described in an accompanying research article.

The concepts of evolution and natural selection remain as some of the most challenging topics to teach. The difficulty in teaching these topics arises from the fact that evolution is difficult to observe, and computer simulations do not always result in a clear understanding of evolutionary principles. Recently, the Avida-ED software has been developed to simulate evolution in a laboratory setting. Unlike other simulations, Avida-ED allows students to manipulate the environment, change the genetics of the virtual organisms, and track offspring in real time. We have demonstrated, by using pretest and posttest questionnaires, that students gained a deeper understanding of evolutionary concepts by using this software. In particular, students showed the greatest increase in their ability to explain evolutionary concepts in answers to open-ended questions. Our results show that Avida-ED could be a useful tool in helping students understand and combat preconceived notions about evolution.

This chapter explores evolutionary concepts important to psychiatry. It discusses concepts including natural selection, adaptation, function, ultimate causation, individual fitness, self-interest, kin selection, reciprocal altruism, and traits and trait variation.

Evolution by natural selection is key to understanding life and of considerable practical importance in public health, medicine, biotechnology, and agriculture. The Next Generation Science Standards (NGSS) include natural selection among several evolutionary concepts that all third-graders should know. This article explores a novel approach to developing and testing curricula for teaching natural selection and related concepts to children. College students developed lesson plans with specific evolutionary learning objectives based on the NGSS and taught them at elementary schools. Learning was assessed with a pre/post-test design, and a subset of students was retested after two years. After just two hours of instruction and active-learning activities, students of all three grade levels tested (grades 3–5) demonstrated substantial improvement in their understanding of evolutionary concepts. Students who were retested in grade 5 scored higher than fifth-graders who had not participated previously. The most challenging concepts for all grade levels were common ancestry and natural selection, but fifth-graders showed more improvement than third- and fourth-graders. If this finding is substantiated by further research, an adjustment to the NGSS schedule might be warranted. Spacing evolutionary biology concepts out might be a better strategy than concentrating them all in grade 3.
