Detailed explanation-1: -Paleontologists were able to detect the particular order in which these organisms have lived. For instance, simpler organisms inhabited older rocks and complex organisms were found in younger rocks. This finding has made them conclude that simple organisms have evolved into more complex organisms over time.

Detailed explanation-2: -Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Detailed explanation-3: -As described by Darwin, evolution occurs by a process called natural selection. In natural selection, some members of a species, being better adapted or suited to their environment, produce more offspring than others, so they pass “advantageous traits” to their offspring.

Detailed explanation-4: -Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
