Module description

Nothing in biology makes sense except in the light of evolution. In this module we will learn why. The incredible biodiversity of our planet can only be understood through understanding the processes that have shaped it: chiefly the process of evolution by natural selection. This is a concept that can be understood by a small child and yet which also hides the power to predict complex and extraordinary patterns in the diversity of life. We will examine the overwhelming evidence for evolution, and how it has shaped every facet of life on our planet.

Module aims - intentions of the module

Evolution by natural selection is among the most profound discoveries in Science. You will be introduced to the basic principles and significance of Evolution. This module will complement Introduction to Conservation and Ecology, Introduction to Vertebrate Zoology, Genetics and Introduction to Invertebrate Zoology modules by introducing you to the processes that result in the wealth of biodiversity evident in the patterns of life on Earth. The module will focus on introducing topics such as selection, variation, speciation, sex and co-evolution.

This module is designed to be a primer on which more detailed second year modules build. The module draws on the research interests of Professor of Evolutionary Ecology Tom Tregenza, whose current research is on understanding natural and sexual selection in the wild and formerly on speciation and laboratory studies of sexual selection. The module includes examples of current research throughout the lectures; how understanding evolution is important to topics such as HIV treatment and includes guest lectures by leading researchers who will discuss topics that are the focus of their current research.

The module contributes to employability through training in problem solving, a skill important in many work environments, and in thinking about how to ask questions to understand the world – do we want to know the mechanism or the underlying cause? Skills will be developed through problem solving in practical sessions and interactive lectures; collaboration in group practical work; reviewing evidence and considering the implications of results. Skills in report writing will be developed through the practical assessment and feedback.

Syllabus plan

Syllabus plan

Lectures will critically examine the formal evidence for the explanation for evolutionary change, including natural and sexual selection, variation, mechanisms of speciation, co-evolution, life history strategies and life in groups. Practical sessions will reinforce concepts covered in lectures, emphasising the nature of scientific enquiry, including how to read scientific papers.

Re-assessment notes

Deferral – if you miss the examination for certificated reasons judged acceptable by the Mitigation Committee, you will be deferred in the examination. The practical report and open book MCQ tests are not deferrable since the feedback provides the correct answers. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination. The mark given for a re-assessment taken as a result of referral will count for 100% of the final mark and will be capped at 40%.
