Explanation:
Detailed explanation-1: -Finally, molecular biology provides data supporting the theory of evolution. In particular, the universality of DNA and near universality of the genetic code for proteins shows that all life once shared a common ancestor. DNA also provides clues into how evolution may have happened.
Detailed explanation-2: -Molecular evidence suggests that the hominin and African ape lines diverged about 6–7 Myr ago. The fossil record of the first possible bipeds dates back over 6 Myr ago in Africa. By 4.2 Myr ago, there is definite evidence of bipedal hominins in Africa (Australopithecus anamensis).
