Question

short note on evolution....!!!???​

Answer 1

Explanation:

$\huge\mathscr\pink{Evolution}$

Evolution is the gradual change taking place all the in living organisms over a very long period of time. The gradual change is a very slow-going process. The changes in specific characters of living organisms for several generations form new species. The nature selects the new species. Besides, the changes occur in stars and planets in space and in biosphere on earth is also taken into the account for evolution.

Explanation:

Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits.Evolution is change in the heritable characteristics of biological populations over successive generations.These characteristics are the expressions of genes that 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. 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.
