| Aims: | To develop an understanding of key concepts in microevolution and macroevolution; to place these in the context of the history of evolutionary thought; to apply these concepts to key problems in evolution; and to understand how they apply to evolution in real populations and in humans.
|
| Learning Outcomes: | After taking this course the student should be able to:
* utilise concepts from evolutionary theory, optimisation theory, behavioural ecology and ecological genetics in understanding ecological and evolutionary issues;
* discuss key concepts in macroevolution and the evolution of modern biodiversity;
* demonstrate an understanding of the role of biological and physical factors in shaping macroevolutionary patterns;
* demonstrate an understanding of the role of mathematical modelling in evolutionary biology;
* demonstrate an understanding of how concepts are applied to understand human evolution.

|
| Content: | The background and reception of The Origin of Species; The age of the earth and the rate of evolution; modelling evolutionary processes; group selection, individual selection, gene level selection; linkage disequilibrium, hitchhiking, disease locus mapping, modifer analysis; measuring and understanding heritability; introduction to quantitative genetics; neutral evolution, the problem of polymorphism and the strength of selection; introduction to molecular evolution: Detecting selection and neutral evolution at the molecular level; selfish elements, genetic conflicts and the corruption of individual level thinking .
Quantitative genetics - connecting variation at the molecular level to variances at the phenotypic level; Influence of inbreeding and non-random mating; Migration, gene flow and metapopulations; Haplotype networks to examine population history; Coalescence and drift; optimality.
Sexual selection and genome evolution; genome-wide screens for selection using comparative primate genomics and the neanderthal genome; population genetic evidence for recent adaptation in human populations; genetic diversity and "The 1000 human genome project"; elucidating molecular adaptation in the post-genomic era.
Why sex? costs and benefits of sexual and asexual reproduction; genetical and ecological approaches to resolving the paradox of sex; constraints on the evolution of asex; insights from geographic parthenogenesis and spatial modelling.
Macroevolution: phyletic gradualism vs. punctuated equilibrium; diversity through time; what drives evolution? the Tree of Life; cladistics; reconstructing evolutionary pathways; molecular clocks; the origins of novelty and the origins of higher taxa; mass extinctions; testing macroevolutionary hypotheses.
