Natural selection is the cornerstone of Darwin's theory of evolution; adaptations are the traits that allow organisms to survive the selection process. This set of resources includes books, articles, and Web links that explore various aspects of these pivotal interrelated concepts.
This activity utilizes the emergence of antibiotic resistance, and mechanisms thereof, to teach essential concepts including natural selection, bacterial gene transfer, mutation, and gene expression. It also provides a connection between course content and modern applications of important concepts. The activity (app. 25 minutes) is intended for introductory students in biology. It is flexible and...
This web unit introduces two kinds of speciation (allopatric and sympatric) through an interactive task: the speciation of a group of tropical angiosperms called Fuchsia. Before starting the task, students are advised to review the definition of allopatric and sympatric speciation by entering "click here".
In the Fuchsia task, the website presents observations and then ask students to...
Report addressing the goals of evolutionary biology, how evolution is studied, how evolutionary biology contributes to society, how it contributes to basic science, and challenges of the future. Written by a working committee representing the major disciplines in evolutionary biology.
This four minute short movie depicts the hatching of a Mojave Desert Tortoise. This is the continuation of a sixty million year process for this threatened species. One of the surprising moments in the movie is when the hatchling tumbles from its shell and is propped up by its yolk. This is an evolutionary adaptation where the young absorb the yolk over several hours and they then use that...
