Description including Unit Aims
This unit focuses on macroevolution, the large patterns of evolution of life on Earth. It is an interdisciplinary unit, drawing material from palaeontology, stratigraphy, sedimentology and evolution. The focus is on tackling deep-time questions concerning global change and the origins of biodiversity. A clear focus is given to current debates and the evidence on either side of debated issues, so students can read widely in the current literature and understand the nature of different kinds of evidence and their meaning. Clear links are made to current environmental crises.
The main aims are:
- to understand changing views on the history of the biosphere
- to summarise current methods of dating and sequencing rocks
- to appreciate the strengths and weaknesses of the rock and fossil records
- to consider different models for the diversification of life
- to understand the contributions of palaeontological data to modern evolutionary theory
- to evaluate the role of catastrophes in earth history
- to apply numerical methods in macroevolution
Intended Learning Outcomes
On completion, you should be able to:
- analyse and apply appropriate numerical methods to macroevolutionary
problems
- document the major stages in the history of life and of the Earth, and present models for diversification of life
- Debate the nature and causes of the major mass extinction events, and how they are studied
- deduce links from longer-term processes to current human-induced crises on the earth
- calculate rates of evolution, estimate models of evolution, compare time series, and apply other numerical methods in macroevolution
- debate evidence for and against gaps in the rock and fossil records
