Many important shreds of evidence are present in our nature which show that evolution has indeed taken place on earth. These pieces of evidence clearly demonstrate that the various new life forms have evolved since the creation of the earth. Some of them are:(i) Fossils (Palaeontological Evidence)(ii) Number and nature of fossils in early rocks.(iii) Distribution of fossils in the successive strata.(iv) The disparity between the past and the present forms of life.(v) Missing Links (Transitional Forms).
