EVOLUTIONARY ORIGINS OF BIODIVERSITY - 2021/2

Module code: BMS1040

Module Overview

This module will consider the diversity of life, from organisms to ecosystems, in the light of evolutionary processes that have shaped the world today.  It will encompass an understanding of the genetic principles underpinning evolution, as well as the classification systems developed in order to understand the diversity of life.

Alternative Assessment

If the practical class is missed an equivalent exercise (1500 word written report) with provided dataset from original assessment.  

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate both their subject knowledge and their transferable (including cognitive and practical / professional) skills.  The former (LO1-5) will predominantly be tested by a short answer style examination (with an element of choice).  The latter (LO6-8) will predominantly be tested in a poster summary of the class practical on biodiversity, which will incorporate elements of species identification and classification, and numerical data presentation.  Effective group working will also be tested in this assessment.

Thus, the summative assessment for this module consists of:

·         Group poster presentation: 30%
Summary of class biodiversity data (using appropriate presentation formats) incorporating an overview of the classification of one exemplar species of choice.  Posters will be submitted online together with a short video to present the content.  Marks will be awarded on the basis of the poster and presentation (90%) and student's participation (peer reviewed, 10%).

·         Examination: 70%
90 min exam; 10 short answer questions and 30 MCQs

Formative assessment and feedback

Students can obtain formative feedback from a variety of sources:


  • verbal feedback following lectures or during tutorials

  • verbal feedback from academics during fieldwork

  • feedback to specific queries via email, with responses being made available to all via SurreyLearn or during tutorials as appropriate

  • automated feedback to SurreyLearn quizzes (overall mark, answers and feedback comments to each question) and answers to worksheets provided for self assessment

  • formative feedback on group working and posters will be available, on request

  • exemplar questions will be made available via SurreyLearn, with peer assessment during final tutorial


Module aims

  • To consider biodiversity from the perspective of evolution
  • To introduce the key concepts of evolution
  • To consider the Tree of Life, focussing on the development of the key features that define cells and organisms
  • To introduce taxonomy and the processes involved in identifying and classifying species

Methods of Teaching / Learning

The learning and teaching strategy is designed to: Stimulate student interest in the diversity of life, where this originates from, and how ecosystems develop and evolve from the physical and biological factors that influence them. Much of the material content will be delivered by lecture, but it is envisage that class discussions will form an element of at least some of these in order to promote deeper thought and understanding. Practical field working sessions will focus on some of the identification and classification skills that underpin ecological study, as well as promoting generic skills such as data presentation and group working.

The learning and teaching methods include:
• Lectures: 29 h
• Tutorials: 2 h
• Practical classes: 7 h
• Poster presentations: 3 h

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
