What is non-human and what is human?

Non-human: that is, things other than people. People and non-human are two relative concepts. Except human beings, others can be classified as non-human, such as cats, dogs, flowers and trees, all of which are non-human.

Man: Homo sapiens, the scientific name, is the only existing species under human beings, and its morphological characteristics are more progressive than that of Homo erectus. It is divided into early homo sapiens and late homo sapiens. Early Homo sapiens used to be called the ancients, living 250,000 to 40,000 years ago. Its main feature is its large brain capacity, which is above 1 300 ml. The brow ridge is developed, the forehead is inclined, the occipital bone is prominent, the nose is wide and flat, and the jaw is prominent.

Human living habits

Homo sapiens is an opportunistic omnivore, showing outstanding originality in extracting, producing, processing and preserving food. Homo sapiens is the only species that can control or fire, and all known homo sapiens groups are cooking.

Regional differences in diet are influenced by the availability of specific environment, cultural traditions (such as food preference and avoidance) and genetic factors. The continuous existence of lactase enables some homo sapiens to eat milk and dairy products in their lifetime, which is an adaptive adjustment to dairy products consumption in the near future and will only play a role in homo sapiens with dairy farming tradition.
