ARISTOTLE
● A famous greek philosopher
● He is regarded as the Father of Biology and also known as the Father of Zoology
● He is widely studied all the aspects of life and its origin, including animal and plant

BRANCHES OF BIOLOGY
● Biology unifies much of natural science
FIELDS DEALING WITH ANIMALS:
● Entomology (study of insects)
● Ethology (study of animal behavior)
● Herpetology (study of reptiles and amphibians)
FIELDS DEALING WITH PLANTS:
● Dendrology (study of trees and their history)
● Mycology (study of fungi)
● Paleobotany (study of plants fossil)
MEDICAL BRANCHES OF BIOLOGY:
● Anatomy (study of the macroscopic structure of multicellular organisms)
