Chapter 1

• Zoology: the scientific study of the behaviour, structure, physiology, classification, and distribution of animals.
• Anatomy study of structure of organisms and their parts
• Cytology structure and functions of cells
• Comparative Genomics and Bioinformatics study of struc and func and evolution of the genetic composition of groups of animals using computer based computational methods
• Ecology inyeraction of organisms w their environment
• Embryology animal from fertilized egg to birth or hatching
• Genetics traits from parent to offspring
• Histology study of tissues
• Molecular Biology subcellular details of struc and func
• Parasitology animals that live inside of a host study
• Physiology func or org and their parts
• Systematics classification of evolutionary interrelationship among animal groups
• Entomology insects
• Herpetology amphibians and reptiles
• Ichthyology fishes.
• Mammalogy animals
• Ornithology birds.
• Protozoology protozoa.
• macroevolution major evolutionary change. The term applies mainly to the evolution of whole taxonomic groups over long periods of time.
• microevolution the change in allele frequencies that occurs over time within a population
• homologous different function same structure
• analogous similar functions but different structures
• Organic Evolution.• A change in the genetic makeup of populations oforganisms over time
• Groups of individuals are more closely related ifthey share more DNA
• Biogeography provides geographical distribution of your organisms and how they are related to each other
• Carl Von Linne: Father of taxonomy, developed the binomial system of naming organisms.
• binomial nomenclature ("two-term naming system")

  Part one is the genus name.

  •Part two is the species epithet
• Ecology.• The study of the relationships between organisms andtheir environment.• Failure to understand ecological relationships amonganimals and their environment has resulted indetrimental consequences
• Human global overpopulation.• Root of all other environmental problems.• Population estimated to be 9.7 billion by 2050
