Explain embryological evidences to support the organic evolution.

Explanation

Paleontological Evidences (Evidences frttm Fossil Record). From the fossil records it has been concluded that evolution has taken place from simple to complex in a gradual manner. In support of it, some evidences are given below : -
(a) The rocks of early era (e.g., Proterozoic) contain less number of fossils than the rocks of later era and only fossils of simple marine invertebrates are in these rock. It is due to the fact that the life first originated in sca as a simple form. So fossils were not in plenty in the beginning as they were in later stage.
(b) The distribution of fossils indicates that fossil forms become more and more complex as we proceed from earliest to the recent rocks.
(c ) On the basis of fossils study, it has been shown that the early organisms were very different from their modern forms, which supports that evolution has been taking place.
(d) The fossil record contains some transitional link forms called missing links (also called connecting links). One such missing links is Archaeopteryx, which is the transitional fossil between birds and reptiles.
Paleontologists have traced out complete evolutionary histories of some animals like horse, camel and elephant and man from the studies of their fossils.
