Biologists investigate life at all levels of organization in order to gain knowledge about the structural and functional complexity of organisms, the origin and evolution of life, and the relationships among organisms and their environments. Moreover, biologists use the information they gather to improve our condition by finding new ways to improve human health and to use our nature resources more safely, efficiently, and effectively. There are many specializations within the field of biology. Evolutionists study the forces that bring about changes in species. Ecologists study the interactions of organisms with their environment.
Embryologists study the developments processes of organisms.
Physiologists study the structure and function of organ systems. Molecular biologists study the metabolic and reproductive process of organisms on the level of biomolecules. At the University of Scranton, courses in the Department of Biology are designed to present the fundamental facts and concepts central to an undergraduate understanding of the living world. In their teaching, the biology professors incorporate other areas of science as well as the liberal arts. The program functions as well to prepare students for advanced study or work in various fields related to biology.
