Mutation theory of evolution explains the role of sudden and heritable changes in organisms that contribute to evolutionary transformation. In physical and biological anthropology, this theory is important because it helps in understanding the origin of biological variations among human populations and the processes that have shaped human evolution. The theory was mainly proposed by Hugo de Vries in the early twentieth century while studying the evening primrose plant (Oenothera lamarckiana). De Vries suggested that evolution does not always occur through small and gradual changes but can also take place through sudden genetic variations called mutations. According to mutation theory, mutations are sudden changes in the genetic material of an organism. These changes may occur in genes or chromosomes and can be passed from one generation
