BECOMING THE FATHER OF BIOLOGY
Aristotle gained this title after his early studies in zoology. His scientific work was monumental for the human understanding of animals. Instead of theorising about different animals and the stages of their life cycles, Aristotle took an empirical approach. This included dissecting birds’ eggs during different stages of development to note changes in embryo growth. His method of classifying species is considered to be his most significant contribution to the field of biology. His work is the first known attempt to classify animals into groups based on similarities they share. In his work titled History of Animals, he wrote about how different animals acquired unique organs and traits based on their specific habitats.
