Many of them were made in the areas of genetics, physiology, and developmental biology. An important area of zoology that developed in the mid-1900's is ethology, the study of animal behavior. The Austrian naturalist Konrad Lorenz helped found this field with his study of the behavior of geese. The majority of these careers require a college education. In addition to zoology courses, students who wish to become zoologists must take courses in mathematics, chemistry, and physics.
Many students also take courses in computer science.
A number of careers in zoology require additional training in graduate or professional schools. Many zoologists teach and conduct research in colleges and universities. Other zoologists work in zoos and museums. Many scientists with zoological training work to make more food available for people. These agricultural scientists work with cattle, hogs, sheep, and other farm animals.
