2. Morphology

3. Physiology

4. Cytology

5. Embryology

6. Ethology

7. Genetics

8. Evolution

9. Ecology

10. Palaeontology

Taxonomy

• Study of the classifications, indentification, and nomenclature of animals
• A.P.De. Condole is the person who coined the term "Taxonomy".

Morphology

• Study of the apperence and internal organs of animals.
• August Schleicher coined the term "Morphology"

• There are two sub divisions in Internal Morphology

Histology

• Study of tissues
• Seen only in Microscope.

Physiology

• Study of the functions and processes of the animals.
• The term "Physiology" was coined by Jean Fernal.
• Eg: Digestive system, etc.

Cytology

• Study of form, and structure of the cells and cell organelles.
• Robert Hooke coined the term 'Cytology'.

Embryology

• Study of the embryoligical devolepment.
• Deals with the formation and devolepment of embryos.
• Study of the events that leads to fertilization, early growth, and differentiation of Zygote into an embryo.
• Aristotle is the father of Embryology.

Ethology

• Study of animal behaviors.
• Lorenz Coined the term "Ethology".

Genetics

• Study of the genes of the animals
• The term "Genetics" was coined by William Bateson.

Evolution

• Study of the orgin of life
• The term "Evolution" was coined by Herbert Spencer.

Ecology

• Study of living organismsin relation to the biotic factors and abiotic environmental factors surrounding them.
• Ernst Hackel coined the term "Ecology"

Palaeontology

• Study of fossils
• H.M.D.Blainville is the person who coined the term "Paleontology".
• In Paleontology there are two types

1. Paleozoology
2. Paleobotany

• Palaozoology- Study of animal fossils
• Palaobotany- Study of plant fossils
