Question

Define evolution ? and also state the character

Answer 1

Character evolutionis the process by which a character or trait (a certain body part or property of an organism) evolves along the branches of an evolutionary tree. Character evolutionusually refers to single changes within a lineage that make this lineage unique from others.

Answer 2

Evolution is change in the heritablecharacteristics of biological populations over successive generations.[1][2] These characteristics are the expressions of genesthat are passed on from parent to offspring during reproduction. Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.[3] Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or rare within a population.[4] It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms and molecules.[
