Description This unit will ensure students are able to understand the core concepts in modern evolutionary theory and the central position that evolution plays in unifying all sub-disciplines of biology. It will also enable students to distinguish the major genetic mechanisms that underpin these theories and critically assess the general importance of genetics in the evolutionary process. In particular, students will gain an in depth knowledge on speciation and population divergence, origin of genetic variation, genetic drift and founder effects, natural and sexual selection, migration, mutation and coevolution, with a major emphasis on genetic mechanisms and the analytical techniques used to assess them. Students may be required to travel to a different campus to undertake this unit.

Learning Outcomes

On successful completion of this subject, students should be able to:
  1. Define evolution and provide supporting evidence for this process;
  2. Evaluate the concepts of natural and sexual selection and how they contribute to biological adaptation and speciation;
  3. Assess the relative importance of neutral and selective processes to evolutionary change;
  4. Critically assess the importance of genes to the evolutionary process and be able to differentiate between the different evolutionary mechanisms;
  5. Combine information on genes and selection to predict the direction and strength of phenotypic evolution;
  6. Describe the ways in which gene interactions can alter the evolution and coevolution of phenotypic traits;
  7. Critically assess and interpret scientific literature, and advances in the field of evolutionary research;
  8. Design, execute, analyse and interpret scientific experiments on genetics and evolution;
  9. Communicate the findings of investigations and experiments in oral and written form;
  10. Analyse the application of evolutionary theory to many modern scientific issues, including (but not limited to) human disease, agricultural breeding, and genetic engineering.
