Matter is in constant motion and motion is inherent in all matter and it is only motion which plays a creative role in the process of biological evolution.
External conditions can affect the speed or rate and direction of change in matter.
No living matter is static and all matter is in constant change. The present living matter is the product of many changes. These changes have taken place for along time. Thus, the present living things developed from pre-existing living things with certain changes. Consequently, the development of living matter is associated with changes in the environment and the genetic material.
