We tested this hypothesis by a standardised comparison of the understanding of natural selection between university freshmen who had completed high level biology secondary education in Flanders or the Netherlands. We used the Conceptual Inventory of Natural Selection (CINS), designed to measure the ...
Evolution by natural selection is the dominant and unifying theme in biology, yet many college students hold alternative conceptions about the topic even after completing general biology. To develop effective instructional strategies and track conceptual understanding, it is useful to have a detailed asse...
Theory shows how sexual selection can exaggerate male traits beyond naturally selected optima and also how natural selection can ultimately halt trait elaboration. Empirical evidence supports this theory, but to our knowledge, there have been no experime
This article reports on a study that assessed knowledge of and misconceptions about natural selection in second-semester biology majors in two classes characterized by different instructional strategies. The active-learning class achieved significant postcourse gains in the number and diversity of key conc...

Natural selection as the main mechanism of biological evolution is a central topic in biology. California science standards require the introduction of the topic in middle school (ages 12-14), so there is a need for a well- designed assessment tool valid for use with this age group. While ...

Natural Selection Within a Species Introduction: Natural selection is the evolutionary process by which the most adaptable individuals survive. An adaptation is an inherited variation that helps an organism to survive. When the organism survives, its chances of reproduction are increased as well as its...
Part 1: Natural Selection Exercise—Generation 1 This exercise illustrates the effect of natural selection on populations of predators and prey. Students, in groups of four, will represent predators, each with a different adaptation for capturing their prey. The prey will consist of different species...
natural selection might have partially suppressed the impact of released population on wild populations. Then, we utilized alterations in the AF of SNPs (ΔAF) to measure their impact on a particular population. The following interpretation and analyses are described at province level. For wild ...
