CH1: introduction

ZOOLOGY
- The study of animals
- Scientific study of behavior, structure, physiology, classification, and distribution of animals

ZOOLOGY SPECIALIZATIONS

Anatomy	Structures of entire organisms and their parts
Cytology	Structure and function of cells
Comparative Genomics and Bioinformatics	Structure, function, and evolution of the genetic composition of groups of animals using computational methods
Ecology	Interaction of organisms with environment
Embryology	Development of an animal from fertilized to birth
Genetics	Mechanisms of transmission of traits from parents to offspring
Histology	Tissues
Molecular Biology	Subcellular details of structure and function
Parasitology	Animals that live in or on other organisms at the expense of the host
Physiology	Function of organisms and their parts
Systematics	Study of the classification of and the evolutionary interrelationships among animal groups

TAXONIMIC CATEGORIES

Entomology	Insects
Herpetology	Amphibians and reptiles
Ichthyology	Fishes
Mammalogy	Mammals
Ornithology	Birds
Protozoology	Protozoa

EVOLUTIONARY PROCESSES

Organic evolution is the change in the genetic makeup of populations

CHARLES DARWIN

Published the evidence of evolution
- e.g. Scale eating cichlids have mouth curved to left/right, Prey can't expect attack from the other side

ANIMAL CLASSFICATION AND EVOLUTIONARY RELATIONSHIPS

Group of individuals are most likely related if they share more DNA

BINOMIAL NOMENCLATURE

Two part name for each species
Perissodus microlepis

ECOLOGY
- Study of the relationships between organisms and their environment

ENDANGERED ANIMALS AND WORLD RESOURCES

GLOBAL OVERPOPULATION

Root of all other environmental problems

WORLD RESOURCES

Overpopulation stresses all resources, leading to climate change, deforestation, water shortages, extinction of animals
