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 in all aspects of its life. WebMar 18, 2024 · Speciation is a central topic in evolutionary biology.

An organism’s DNA affects how it looks, how it behaves, and its physiology. So a change in an organism’s DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur. WebSince all cells in our body contain DNA, there are lots of places for mutations to occur; however, not all mutations matter for evolution. Somatic mutations occur in non-reproductive cells and so won’t be passed on to offspring. For example, the yellow color on half of a petal on this red tulip was caused by a somatic. hemming a shirt
