1. Life is a configuration of time and space, not a material entity (the bricks of life—atoms, have been replaced many times in metabolism, but the flow of entities does not affect the life it constructs); 2. Life can reproduce itself (except mules); 3. Life forms can grow; 4. Life has self-describing information storage; 5. There is a metabolic effect between the living body and the outside world (the life of a virus depends on the metabolism of the host, so the virus can only be regarded as a half-life); 6. Life has a functional influence and regulation on the environment, and the body can also generate and control its internal microenvironment;

7. The various parts of the living body are interdependent; 8. The living body is stable to the small disturbance of the external environment; 9. Life must have the ability to evolve.Not referring to individuals, but having this ability in terms of their race.
