Summary module description:

Aims:
Students on this course will be introduced to ideas about the selfish genetic and adaptive forces that shape the evolution of genes and genomes. They will study topics and current controversies in evolution and phylogeny. Students will learn about the organisation and evolution of genomes, and especially about selfish or parasitic genomic elements that comprise the majority of the DNA in our genomes. Practical work associated with the course will give students experience in constructing phylogenetic trees as these will be used to help investigate questions about evolution.

Assessable learning outcomes:
• Knowledge of the evolutionary forces that shape genomes
• Knowledge of how phylogenetic trees have helped to understand fundamental questions of biological evolution
• Awareness of current controversies in the field

Additional outcomes:
Students will develop their presentation and communication skills, and gain experience in critical analysis of the peer-reviewed primary scientific literature.

Outline content:
This course will give an introduction to phylogenetics (what phylogenies are, how they are constructed, and what they are used for) and then move on to consider topics in evolutionary genetics, especially those that can be investigated using phylogenies. Topics covered include sequence analysis and methods of detecting natural selection, transposable elements and other genomic parasites, the evolution of the genetic code, the evolution of novelty, the evolution and diversity of genetic systems, the evolution of HIV, and the evolution of non-genetic replicators.

Brief description of teaching and learning methods:
The course is arranged around weekly lectures, each followed by a seminar, practical exercise or student-led seminar based on controversies in the recent peer-reviewed scientific literature. Students are encouraged to contribute to lectures via questions and answers. There is also a practical covering the basic concepts of phylogeny construction.

Penalties for late submission:
The Module Convener will apply the following penalties for work submitted late, in accordance with the University policy.

  • where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
  • where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

  • The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
    You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

    Length of examination:
    Two hour paper, requiring answers to 2 questions out of 4.

    Requirements for a pass:
    A mark of 40% overall.

    Reassessment arrangements:
    Re-examination in August / September only
