This study examines how third-graders' conceptions about the origin of species are affected by formal instruction and whether children can learn not only about evolution but also about natural selection. We interviewed the same group of third-grade children (8-9 years old) twice, before and after following a curriculum about these topics.…

Tree thinking, the understanding of the evolutionary relationships between organisms depicted in different types of tree diagrams, is an integral part of understanding evolution. Novice learners often read tree diagrams differently from specialists, resulting in diverse interpretations of the relationships depicted. The aim of this study is to…

Despite the ubiquitous use of anthropomorphic language to describe biological change in both educational settings and popular science, little is known about how anthropomorphic language influences children's understanding of evolutionary concepts. In an experimental study, we assessed whether the language used to convey evolutionary concepts…

Since 1992 C. J. Rogers has lived with wolves and studied their societies at Raised by Wolves, a licensed, nonprofit research sanctuary situated in a high valley of New Mexico's Zuni Mountains, not far from the Four Corners. Rogers, who has taught at Northeastern Illinois University and Western New Mexico University, holds doctorates in both…

Museum visitors are an ideal population for assessing the persistence of the conceptual barriers that make it difficult to grasp Darwinian evolutionary theory. In comparison with other members of the public, they are more likely to be interested in natural history, have higher education levels, and be exposed to the relevant content. If museum…

Investigations of people's understanding of the evolution of species have focused mainly on secondary school and university students. Very few investigations have taken into consideration younger students, and none have related children's ideas about the origin of species to formal instruction on this topic. To help fill this gap, the present…

Historians of science have pointed to essentialist beliefs about species as major impediments to the discovery of natural selection. The present study investigated whether such beliefs are impediments to learning this concept as well. Participants (43 children aged 4-9 and 34 adults) were asked to judge the variability of various behavioral and…
