... semester to develop and link core concepts. A central theme in evolutionary biology is determining if complex biological traits represent adaptations that arose by natural selection. The instructional model presented here engages students in a step-by-step process to answer this question of adaptation...

... on the evolutionary perspectives of what might be causing human ear infections, as well as the role of beneficial species of gut bacteria in maintaining a healthy immune system. It is advantageous for students to know about natural selection and coevolution before using the case study. An ear infection...

...Douglas Allchin This classroom activity highlights how evolution by natural selection is nonteleological —that is, not guided by need, by organismal intent, by inherent progress, by an external ideal, or by any observable purposive agent. Rather, it is driven by chance opportunity, environmental...
