Laboratories
1) Laboratory sessions begin next Monday (Sept.
20). Please bring your student card (with WHMISsticker) to the first session. If you do not have a
sticker, please attend a WHMIS training session
before your first laboratory session.
2) You will need a laboratory manual, a dissection
kit, lab goggles, a lab coat, and plain paper for
drawing diagrams.
3) The laboratory part of the course accounts for35% of the final grade. This mark is based on
laboratory assignments and quizzes, and a test at
the end of the term.

Lab exam will be comprehensive and willcover all of the material learned in the labs
bell ringer slide show format
Will need to identify organisms, namestructures and their functions, and knowaspects of life history
Make detailed diagrams of organisms seenunder the microscope, consider taking photosof dissections

What is zoology?
Study of animal biology Covers aspects of animal physiology,
ecology, behaviour, evolution, genetics, and
phylogeny.
What are animals?
Eukaryotic organisms that depend on eating
other organisms for nutrition

Our exploration of zoology will be guided by
a number ofthemes:
Phylogeny and evolutionary relationships
Body plan and organization:
-Unicellular? multicellular?
-Radial/ bilateral symmetry?
-Support
-Body cavity: acoelomate? coelomate?

Themes:
Habitat: aquatic: marine? freshwater?
terrestrial: arid? tropical?
freeliving or parasitic?
Life cycle:
Sexual/asexual reproduction? Life stages

Classification and systematics
We need a way to categorize and
classify organisms
Oldest system: plant or animal
8/8/2019 1. Intro-Online Version
13/22
Classification vs. systematics
Classification is the assignment of
organisms to categories based oncommon characteristics
Old way of categorizing animals
Systematics assigns organisms toclasses based on shared evolutionary
descent
N
ewer way that recognizes the importanceof evolutionary relationships
8/8/2019 1. Intro-Online Version
14/22
Basis for categorization
Comparative morphology: shapes of
bones, cells, tissues, embryonicdevelopment
Comparative biochemistry: metabolicpathways, proteins and DNA sequences
Comparative cytology: number andshape of chromosomes

The goal of systematics is to come upwith monophyletic groups (clades):
taxonomic groupings that include all thedescendants of a common ancestor

Five kingdom system
Monera (bacteria) lack a nucleus
(prokaryotes)
Protista unicellular eukaryotes
Fungi
feed by absorption includes molds and
yeasts
Plantae multicellular
photosynthetic
Animalia most ingest food
parasitic exceptions

Three domain system
Newer than the five kingdom system
Based on genetic information
Recognizes three domains of life:
Bacteria,Archaea,Eucarya
Eucarya includes plants, animals, fungi
and different kinds of protists
