BIOL2451: EVOLUTION

Please ensure you check the module availability box for each module outline, as not all modules will run in each academic year. Each module description relates to the year indicated in the module availability box, and this may change from year to year, due to, for example: changing staff expertise, disciplinary developments, the requirements of external bodies and partners, and student feedback. Current modules are subject to change in light of the ongoing disruption caused by Covid-19.

Prerequisites

  • Level 1 Organisms and Environment (BIOL1161); Level 1 Genetics (BIOL1171)

Corequisites

  • At least one other Level 2 Biological Sciences Module

Excluded Combinations of Modules

  • None

Aims

  • To study the molecular basis of evolutionary change.
  • To study the processes by which evolutionary change takes place.
  • To relate the diversity of living organisms to the evolutionary processes that promote change and conserve function

Content

  • Genome structure and mutations the raw material of evolution.
  • Evolving phenotypes and the interaction between evolution and development.
  • How populations evolve by natural selection and genetic drift.
  • The concept of the species and how new species evolve.
  • Interpreting evolutionary histories (phylogenies) and species radiations.

Learning Outcomes

Subject-specific Knowledge:

  • The nature of mutations and when they may lead to evolutionary change.
  • Knowledge of evolutionary processes in natural populations.
  • Knowledge of the nature of species and the process of speciation.
  • Knowledge of the major patterns of organismal diversity and the mechanisms that determine species radiations.

Subject-specific Skills:

  • To be able to understand and apply basic mathematical principles to an understanding of evolutionary processes.
  • To be able to apply evolutionary principles to the classification of biodiversity.

Key Skills:

  • Numeracy, in data analysis, and calculations involved in data handling problems.
  • IT skills, in use of software packages.
  • Communication skills, using the written word and graphics, involved in evolution practical reports.
  • Team work.
  • Self-motivation, in self-guided learning.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

  • Lectures deliver subject-specific knowledge.
  • Workshops reinforce subject-specific knowledge and understanding gained from lectures and the development of key and subject-specific skills.
  • Practical Exercises allow students to utilise subject-specific knowledge gained from lectures, and support the development of key and subject-specific skills.
  • Tutorials give enhancement of the student learning experience, supporting attainment of all learning outcomes.
  • Self-guided learning contributes to subject-specific knowledge and self-motivation.
  • Practical Exercises are based on subject-specific knowledge and demonstrate subject-specific skills in understanding experimental work and data analysis.
  • Problem Exercises (Data Handling) demonstrate subject-specific skills in data handling and key skills in numeracy.
