BIOL6090 Evolution and Development

Module Overview

This module will deliver a comprehensive analysis of the topics associated with evolutionary developmental biology. This will involve exploring the theory of evolution; embryology and molecular pathways of development; what the fossil record tells us about development and the timings of emergence of species, body plans and morphological characters; how this can be used to produce trees elucidating evolutionary relationships. This module will link traditional 19th century topics of evolutionary theory and embryology with 21st century insights from phylogenetics, developmental and molecular biology and palaeontology

Aims and Objectives

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • Describe the relationship between evolution and development.
  • Outline the approaches used to detect phylogenetic relationships using the range of techniques and tools available.
  • Describe the developmental patterns and function of toolkit genes Hox and Pax6 in model organisms.
  • Describe how gene regulation plays a key role in evolution.
  • Explain the role of gene co-option in evolution eg. Hox in anterior-posterior patterning (ancestral) and its co-option to patterning the tetrapod limb.
  • Describe how signalling molecules contribute to the development of the body plan.
  • Explain how the fossil record allows soft minimum/maximum dates to be applied to species divergence and the appearance of morphological characters

Learning and Teaching

Teaching and learning methods

The module is delivered principally via lectures taking their titles from Evolution a developmental approach, by Wallace Arthur (2011), supported by informal discussions with lecturers and independent study of recommended reading material. Lectures will take the title of chapter in the book, which should be read before the lecture (element of flip learning). The lecture will then elaborate on the topic of that chapter, or examine exciting developments in the field around the topic.
