WebMutations are changes in the information contained in genetic material. For most of life, this means a change in the sequence of DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, its physiology — all aspects of its life. So a change in an organism's DNA can cause changes WebDarwin's concept of natural selection was based on several key observations: Traits are often heritable. In living organisms, many characteristics are inherited, or passed from parent to offspring. (Darwin …
