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.
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
- 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

Means of Assessment
|MEANS OF ASSESSMENT
|Final laboratory examination
After completing this course, students should be able:
- To describe the general principles of vertebrate classification and phylogeny, and characteristics of the major chordate taxa.
- To explain the diversity of vertebrate forms and compare and contrast the unity which exists within this diversity.
- To explore anatomical and physiological principles by studying form and function relationships in an evolutionary context.
- To describe how organisms interact with their environments and how environmental conditions modulate these interactions through adaptive mechanisms.
- To indicate how the scientific method is used to advance our knowledge of vertebrate anatomy and physiology.
- To be able to use the general principles of biology to discuss current issues and ideas.

Below shows how this course and its credits transfer within the BC transfer system.
A course is considered university-transferable (UT) if it transfers to at least one of the five research universities in British Columbia: University of British Columbia; University of British Columbia-Okanagan; Simon Fraser University; University of Victoria; and the University of Northern British Columbia.
