Description

Aims

Land plants originated from their aquatic algal ancestors around 470 million years ago. This unit explores how plants originated and diversified. It aims to give students a framework to discover the developmental and genetic basis of changes in plant form and function that occurred during evolution, discuss the ecological context for such changes, and identify their relevance to engineering the architecture of future plant forms.

Description

The unit is structured to give an overview of the evo-devo research field and introduce core principles of the evo-devo field. Teaching will take place on how genes enable the major organ systems of vascular plants to arise and will then build on these principles to explain how seed and flowering plants originated and diversified, with a focus on the radiation of flowering plants.

Intended learning outcomes

After taking the unit students will be able to:

  1. Describe the organography of diverse plant forms sampled across the plant tree of life
  2. Discuss the developmental and genetic mechanisms by which plant form arises
  3. Design rigorous testable hypotheses of morphological change in plant evolution
  4. Explain why the mechanisms regulating plant form are relevant to humans.

Teaching details

Lectures, directed reading, research and/or problem-solving activities; and independent study.

Assessment Details

Summative written assessment, with one essay question to be selected from a choice of two.
