The Life Sciences involve the scientific study of living organisms like plants, animals, and human beings. While biology remains the centerpiece of the life sciences, technological advances in molecular biology and biotechnology have led to a burgeoning of specializations and new, often interdisciplinary, fields.
Agriculture - Agriculture was key in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science.
Botany - Botany covers a wide range of scientific disciplines including structure, growth, reproduction, metabolism, development, diseases, chemical properties, and evolutionary relationships among taxonomic groups.
Paleontology - As a "historical science" Paleontology tries to explain causes rather than conduct experiments to observe effects. Paleontologists have discovered much of the evolutionary history of life, almost back to when Earth became capable of supporting life.
