Scientific study of animal life
True or False: Zoology is built on centuries of animal observations on the human
world.
False. Zoology is built on centuries of human observations on the animal world.
True or False: Zoology is the documentation of the uniformity of animal life, in
which, the observations are organized in a non-systemic way through
collaboration of thousands of zoologist working in some parts of the world.
False. Zoology is the documentation of the diversity of animal life, in which, the

zoologist in every part of the world.
Aim of Zoology
To (1) explain animal diversity and (2) how animals perform the basic processes of life
that permit them to inhabit diverse environments.
What separates a living from a non-living?
The historical continuity, the history of common descent with modifications.
What are the eight general properties of living systems?
Chemical Uniqueness, Complexity of Hierarchal Organization, Reproduction,
Possession of a Genetic Program, Metabolism, Development, Environmental
Interaction, Movement
Unique complex atomic organization
Chemical Uniqueness
Constituent molecules and chemical bonds of non-living matter does not differ on
the living matter. How do they differ then?
Complex organization in and out of cells
Configuration of atomic macromolecules give rise to
Unique emergent properties
Examples of unique emergent properties
enzymes, transport, storage, defense
Living systems assembles?
Macromolecules
What propert gives Venus an indicator of life?
Phosphine
Hierarchy of Life
Cell - Tissue - Organ - Organ System - Organism
Arise from interactions of components that otherwise would'nt manifest in each
component
Emergent Properties
Living organisms come from pre-existing organisms
