This unit examines contemporary theories and concepts in ecology and evolutionary biology in terms of the ways that these ideas are used to inform both scientific progress and public debate. Modern biological theories are profoundly affecting the ways that we view developmental biology, macroevolution, conservation, the impacts of introduced species, and the role of Darwinism in social policy. The unit is designed to develop critical thinking and debate about selected, currently topical concepts in Biology through a series of structured readings, self-guided research and group discussions. The emphasis is on improving skills in finding and collating scientific evidence, understanding and evaluating competing arguments, and integrating and presenting scientific arguments in a professional manner. As such the unit provides a unique opportunity to explore a current topic in more depth than is possible in Level 200 units. By doing so, you should develop the skills of critical thinking and scientific debate that will be useful in getting more out of Level 300 units and which are essential for honours and postgraduate units.
