BiologyHistoryThe earliest of roots of science, which included medicine, can be traced to ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions shaped ancient Greek natural philosophy. Ancient Greek philosophers such as Aristotle (384–322 BCE) contributed extensively to the development of biological knowledge. He explored biological causation and the diversity of life. His successor, Theophrastus, began the scientific study of plants. Scholars of the medieval Islamic world who wrote on biology...
Well-beingWell-being is what is non-instrumentally good for a person. Also called welfare and quality of life, it is a measure of how well life is going for someone.

For example, zoology is the study of ...
