Sociality pervades all aspects of biological existence, from genes to human civilisations. For example, genes aggregate into genomes, cells into multicellular organisms, and insects into colonies. At each level in the hierarchy of biological organisation, these changes represent a major transition in evolution, whereby a new level of 'individuality' emerges, and the behaviours of group members changes as they become increasingly committed to specific phenotypic roles. Recently, there have been important theoretical and empirical advances in our understanding of the proximate (mechanistic) and ultimate (functional) processes underlying sociality, and the extent to which there is a common evolutionary framework that explains sociality across the hierarchy of biological organisation.
The primary aim of the course is to explain the unified theory of social evolution that applies from genes to civilisations. This theory can be use to underpin the key phases in the transition to social living. Broadly, these are: (a) social group formation, including the costs and benefits of giving up independence to live in a group; (b) social group maintenance, including the processes that limit exploitation and conflict within and between groups; and (c) transition to complex sociality, including the shift from individual-level organisation to self-organisation. The concept of increasing levels of commitment to specific roles by individual group members will be explored, through these different stages.
The secondary aim is to explore not only the functional understanding of sociality (which is well-developed) but also the mechanistic basis of social evolution. In recent years, substantial progress has been made with respect to the latter, especially how the genome accommodates the evolution of higher-level individuality. Here, we will draw on the recent sociogenomics literature that seeks to explain sociality in molecular terms. Using examples from across the hierarchy of biological organisation, we will determine to what extent social behaviour is underpinned by the same conserved molecular processes and the emerging role of genomic novelty in social evolution and behaviour. This gene-level approach can help us attain an integrated understanding of sociality, across levels of biological organisation, through integrated interrogation of proximate and ultimate questions.
Students who have completed this course will have:
Lectures, directed reading, research and/or problem-solving activities; and independent study.
Summative written assessment, with one essay question to be selected from a choice of two.
If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.
If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. BIOL30003).
How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours
of study to complete. Your total learning time is made up of contact time, directed learning tasks,
independent learning and assessment activity.
See the Faculty workload statement relating to this unit for more information.
Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit.
The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an
assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates
within the Regulations and Code of Practice for Taught Programmes.
