Human Biology is the scientific study of living organisms and their interactions with the nonliving world, with a focus on human beings. Students of Human/ Integrative Biology will examine the structures and functions of all living organisms, from microbes to human beings. Some of the sub-disciplines include morphology, taxonomy, physiology, cell biology, biochemistry, genetics, evolution and ecology. The Human Biology Program is designed for students with a strong interest in the Health Sciences, incorporating biology, psychology, physical science and social science courses with a human health focus. The Specialist level is a rigorous program that provides excellent preparation for the MCAT and other Health Science aptitude tests. Laboratory work is an integral component of the biology programs. The labs are sized to offer a small student/demonstrator ratio (maximum 20), which allows for close interaction and positive teaching and learning experiences. The Biological Sciences at UTSC offer several distinct specialized programs. Students can choose from the Specialist Programs in Integrative Biology, Cell & Molecular Biology, Human Biology or Biodiversity, Ecology and Evolution, or the Major Programs in Biology, Human Biology or Biodiversity, Ecology and Evolution.
