This site – aimed at first year undergraduates from a wide range of backgrounds, including those without biology A-level – introduces the basics of evolution.
Before we learn more about evolution, let's get a handle on the history of life. This site provides an overview of important evolutionary milestones in the first 3000-million years of life. This, and all subsequent sites, are written for second year undergraduates.
How do lineages evolve over tens of millions of years? This session looks into the patterns and processes of evolution in deep time, and across the tree of life.
Here we chart the history of extinctions over geological time, mass extinctions in the past, and the currently occurring mass extinction.
This site provides an introduction to ecology in deep time: both of fossil species, and of extinct communities.
At a time when human activities are impacting on every part of the biosphere, the fossil record can provide context for – and help us – conserve living species.
How are fossils distributed in time and space? What can this tell is?
Life started in the ocean. In this lecture we see how, and when, life evolved to live on land.
