Evolution, in terms of biology, consists of the genetic, anatomical and functional changes that occur in individuals of different species, acquiring useful characteristics that replace unfavorable characteristics, due to processes such as natural selection, proposed by <u>Charles Darwin</u>.
<u>Biological evolution</u> raises the existence of a common ancestor, from which all current known species are known, and an evolutionary line for each of those species. Evolution is considered the basis of <u>biodiversity</u>, due to the genetic changes it has produced over many years.
