Many students begin their path to a zoology degree with basic science courses such as biology and chemistry. These courses are usually prerequisites to more advanced science classes, such as human anatomy and physiology.
Students learn about the roles genetics plays in the development of both humans and animals. Topics may include population, molecular and classical genetics. An evolution course is often required, which teaches students about the gradual changes that occur in animal populations.
Students must typically take courses such as entomology, the study of insects, and ichthyology, the study of fishes. Other possible courses include the study of unicellular organisms, called protozoology, and herpetology, which focuses on reptiles and amphibians. Classes about mammals and birds are also required.
Several ecology courses may need to be taken for a zoology degree. Ecology focuses on how organisms relate to their environment. After a basic ecology class, students may take specialized courses, such as aquatic or tropical marine ecology.
