Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] it occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]. The history of life on earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. earth formed about 4.5 billion years ago (abbreviated as ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 ga. [1] [2] [3] the similarities among all known present day species indicate that they have diverged through the.
