Overview

Course Description
The course will examine the comparative morphology of vertebrate groups within an evolutionary and phylogenetic context. Topics will include an introduction to the phylogeny of the vertebrates, and a comparative study of systems for locomotion, nervous and sensory perception, respiration, circulation, digestion, thermoregulation, excretion and reproduction.
Course Content

1. OVERVIEW OF VERTEBRATE CLASSIFICATION

  • Introduction of the major vertebrate phyla and characteristics for each
  • Introduction to vertebrate phylogenetics
  • Diversity and distribution of vertebrates
  • Biological design principles linking form and function

2. NERVOUS & SENSORY SYSTEMS

  • Evolution and organization of nervous systems
  • Basic neural and sensory physiology
  • General and special sensory organs
  • Communication and social behaviour

3. PROTECTION, SUPPORT & LOCOMOTION

  • Integumentary adaptations
  • Skeletal system adaptations and types of movement (e.g. crawling; burrowing; running; swimming; jumping; flight)
  • Introduction to muscle action and basic biomechanics

4. FOOD ACQUISITION & DIGESTION

  • Vertebrate feeding mechanisms, specializations of teeth and jaws
  • Functional components of the digestive system
  • Digestion in herbivores vs. carnivores

5. RESPIRATORY & CIRCULATORY SYSTEMS

  • Comparison of various respiratory organs
  • Diffusion rates and counter-current exchange
  • Evolution of swim bladders
  • Water to land transition; aquatic vs. terrestrial respiratory mechanisms
  • Comparison of vertebrate cardiovascular systems
  • Matching heart structure and blood flow with environmental demands
  • Structure and function of the lymphatic system

6. EXCRETION

  • Comparison of vertebrate kidney structure and function
  • Comparison of modes of excretion in relation to lifestyle & habitat
  • Osmoregulation – regulating water and salt balance

7. TEMPERATURE, SEASONS & CLIMATE

  • Ectotherms and endotherms
  • Structures and mechanisms involved in thermoregulation
  • Homeostasis and acclimatization
  • Adaptations for extreme climates: adaptive heterothermy, thermogenesis and freeze-tolerance

8. REPRODUCTION & GROWTH

  • Reproductive strategies & behaviours
  • Fertilization mechanisms (internal vs. external)
  • Mechanisms and structures involved in sexual reproduction
  • Early development and comparative embryology
  • Oviparity vs viviparity and parenting behaviour
Learning Activities

Learning Outcomes

After completing this course, the succesful student will be able to:

  1. Describe the general principles of vertebrate classification and phylogeny, and characteristics of the major chordate taxa.
  2. Explain the diversity of vertebrate forms and compare and contrast the unity which exists within this diversity.
  3. Explore anatomical and physiological principles by studying form and function relationships in an evolutionary context.
  4. Describe how organisms interact with their environments and how environmental conditions modulate these interactions through adaptive mechanisms.
  5. Indicate how the scientific method is used to advance our knowledge of vertebrate anatomy and physiology.
  6. Use the general principles of biology to discuss current issues and ideas.
