In 1988, Robert O'Hara coined the now ubiquitous phrase "tree thinking" to highlight the importance of cladistics for proper evolutionary reasoning. This accessible phrase has been taken up widely in the professional, popular, and educational literatures, and it has played an important role in helping spread phylogenetic thinking far…

Previous research has shown that students employ intuitive thinking when understanding scientific concepts. Three types of intuitive thinking--essentialist, teleological, and anthropic thinking--are used in biology learning and can lead to misconceptions. However, it is unknown how commonly these types of intuitive thinking, or cognitive…

Genetic variation is historically challenging for undergraduate students to master, potentially due to its grounding in both evolution and genetics. Traditionally, student expertise in genetic variation has been evaluated using Key Concepts. However, Cognitive Construals may add to a more nuanced picture of students' developing expertise. Here, we…

Evolution is the central concept of biology and key to a comprehensive understanding of any complex biological interaction. It has proven to be a particularly difficult subject for both teachers and students. Hybrid teaching environments have the potential to support students in learning about complex topics and simultaneously enable researchers…

This study analyzes the effect of different instructions on threshold concepts within material covering natural selection on students' use of concepts about evolution. Moreover, it examines students' use of concepts as interconnected networks when reasoning about natural selection and analyzes how these concepts relate to each other regarding…

The importance of introducing evolution in primary schools has been highlighted in evolution education research, but few studies have approached the understanding of evolution of prospective teachers who are being prepared to teach at primary school level. The present exploratory study aims to answer three research questions about the ability of…

Understanding natural selection requires mentally linking various key concepts and processes. Many students find it difficult to construct scientific explanations about natural selection and might display misconceptions. Our study aimed to investigate the understanding of natural selection and the existence of teleological or other misconceptions…

Here, we present a ten-year assessment of core concept retention, with an emphasis on evolution, by senior biology majors at a small, private liberal arts college. For concepts that are regularly revisited throughout the biology curriculum, we found that knowledge retention was robust. However, for concepts that are encountered only during the…

Ernst Haeckel (1834-1919) is most recalled in the history of biology for his Recapitulation Theory and the allegedly fudged illustrations of embryos that he presented in support of that case. Less well known is his contribution to abiogenesis theory, which he incorporated into evolutionary theory. In so doing, Haeckel, a vitriolic atheist, was…

Phylogenetic trees are important tools for teaching and understanding evolution, yet students struggle to read and interpret them correctly. In this study, we extend a study conducted by Catley and Novick (2008) by investigating depictions of evolutionary trees in US textbooks. We investigated 1197 diagrams from 11 German and 11 United States…

This paper examines how Buddhists in America have been able to integrate evolution into their worldview to a much greater extent than other religious groups in the United States. Not only is evolution and science in general in line with the main teachings of Buddhism, but Buddhist teachers in the US have consistently encouraged Buddhists to…

Students possess alternative conceptions of many science topics, and these conceptions can act as obstacles for learning scientific concepts. In the field of biology education, students' alternative conceptions of evolution have been widely investigated. However, there is little research on how teachers diagnose and deal with these alternative…

In evolution education, misconceptions about evolutionary concepts impact students' learning. Much research exists on assessing knowledge about evolution using different instruments. The current article introduces the KAEVO 2.0 instrument, which includes various evolutionary aspects representing microevolution and macroevolution. The introduced…

There is substantial body of literature in science education focusing on students' understanding of the theory of evolution by natural selection. However, despite decades of research on the evolution versus creationism debate there is still widespread concern that particular misconceptions about evolution persist. The study aimed to recalibrate…

An understanding of biological variation is important for understanding ecological interactions, ecosystem function, and species' response to environmental change. Biological variation is essential to species survival because natural selection acts upon the phenotypic variation within a population: the more varied the population's genetic…
