Study Notes
Zoology Overview
- Zoology combines "zoon" (animal) and "logy" (study), focused on understanding animal life, their properties, populations, habitats, and characteristics.
Structural Zoology
- Comprises the study of animal structures:
- Morphology: Examines form and shape of organisms as a whole.
- Anatomy: Investigates organism structures revealed through dissection.
- Histology: Studies microstructures and functions of tissues.
- Cytology: Explores structures and functions within cells.
Developmental Zoology
- Focuses on animal development:
- Embryology: Studies growth within the fertilized egg; identifies homologous (same origin, different function) and analogous structures (different origin, same function).
- Ontogeny: Examines individual development.
- Genetics: Analyzes heredity and variation in organisms.
Functional Zoology
- Centers on animal functions:
- Physiology: Studies living processes and functions in animals.
- Animal Behavior: Investigates responses to environmental stimuli; includes irritability, taxis (directional movement), and tropism (plant equivalent).
- Various types of taxis classified by stimuli:
- Thigmotaxis: Response to touch.
- Geotaxis: Response to gravity.
- Thermotaxis: Response to temperature.
- Rheotaxis: Response to currents.
- Heliotaxis: Response to light.
- Hydrotaxis: Response to water.
- Phototaxis: Response to artificial light.
- Chemotaxis: Response to chemicals.
- Galvanotaxis: Response to electricity.
- Chromotaxis: Response to color.
Systematic Zoology (Taxonomy)
- Classifies animals into sub-disciplines:
- Protozoology: Study of one-celled organisms.
- Ichthyology: Study of fishes.
- Herpetology: Study of reptiles.
- Entomology: Study of insects.
- Ornithology: Study of birds.
- Conchology: Study of shells.
- Helminthology: Study of worms, especially parasitic.
- Parasitology: Study of parasitic organisms.
- Malacology: Study of mollusks.
- Mammalogy: Study of mammals and their characteristics.
Distributional Zoology
- Studies the distribution of animals:
- Zoogeography: Examines animal distribution across air, water, or land.
-
Ecology: Investigates relations between animals and their environment, including:
- Convergence: Different groups develop similar forms due to environmental similarities (e.g., fish-like structures).
- Divergence: Same groups assume different forms due to environmental differences (e.g., mammals adapting to water or air).
Historical Zoology
- Focuses on the history of animal life:
- Paleontology: Studies fossils and their distribution over time.
- Phylogeny: Investigates development of specific groups or races.
- Evolution: Examines the origin and differentiation of animal life.
Economic Zoology
- Explores the economic value of animal species for human benefit.
Medical Zoology
- Investigates the medical relevance of animals:
- Parasitology: Studies parasitic organisms.
- Pathology: Analyzes nature, symptoms, and causes of diseases.
Life Definition
- Life is the totality of all bodily activities and functions of an organism.
Theories on the Origin of Life
- Discusses various theories, including Divine or Special Creation.
