Life science, also known as biology, is a science that studies the law of life activity, the nature of life, the law of life development and the relationship between various organisms and between organisms and the environment.

Life sciences (1 life sciences) is a relatively young science in the whole science family. The term life science began to appear in the mid-20th century and gradually became widely used. Even the earlier word biology was coined in the early 9th century/kloc-0. But biological knowledge belongs to the earliest accumulated knowledge system of human civilization.

The development of agriculture and other aquaculture about 1 10,000 years ago contributed to the settlement of human life and the emergence of human civilization. Early humans around the world accumulated rich biological knowledge in medicine, agriculture and animal husbandry. Help people cope with and treat diseases, find and store food, domesticate wild animals and plants, cultivate crops and develop animal husbandry.

Early philosophers were usually masters of biological knowledge. For example, Aristotle, an ancient Greek saint, wrote books such as Natural History of Animals, Components of Animals and Reproduction of Animals, and put forward his own views on early animal and plant observation and animal classification.
