Evolution: Making Sense Of Life (BIOL20001)

It is widely held that nothing in biology makes sense, except in the light of evolution. But evolutionary theory is crucial not only for making sense of organic diversity, but also for helping us understand and manage our interactions with other organisms: antibiotic and insecticide resistance, disease virulence, fisheries decline, spread of invasive species, human behaviour and life-histories are all informed by a knowledge of the processes of evolution. This subject will reveal the ubiquity of biological evolution in both natural and human modified environments. It will describe and explain the agents of change— drift, migration and selection, and show their effects on both single and multiple gene traits, and on the phylogenetic relationships of species. The subject will introduce co-evolutionary processes, which are critical for understanding traits that evolve through interactions between species, including humans. Particular topics will include (but not limited to): heritable variation; agents of evolution; artificial, natural and sexual selection; phenotypes and quantitative genetics; phylogeny, speciation and the tree of life; and antagonistic and mutualistic co-evolution. The subject will emphasise both the outcome and process of scientific research leading to our understanding of evolutionary processes, drawing on examples from across the diversity of life.
