Branches of science much as it involves a clearly biological aspect. While biology remains the centerpiece of life science, technological advances in molecular biology and biotechnology have led to a burgeoning of specializations and new, often interdisciplinary, fields. "Biology" is the branch of natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. Biology is a vast subject containing many subdivisions, topics, and disciplines. Zoology, occasionally spelled zoölogy, is the branch of science that relates to the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both
Primatology uninfluenced by human interference. There are three methodological approaches in primatology: field study, the more realistic approach, laboratory study, the more controlled approach, and semi-free ranging, where primate habitat and wild social structure is replicated in a captive setting. Field is done in natural environments, in which scientific observers watch primates in their natural habitat. Laboratory study is done in controlled lab settings. In lab settings, scientists are able to perform controlled experimentation on the learning capabilities and behavioral patterns of the animals. In semi-free ranging studies, scientists are able to watch how primates might act in the wild but
