Answers
(a) Actually if we see some species like human beings, frog, fish, rabbit... etc.... they are come from common ancestor.... (by embryology).
some million years evolution was took place...
ex: about red beetles and green beetles...... (we known)
Due to evolution same type of species in different areas changed in consuming food, habitats, way of life..... this classified living beings into many groups.....
Thus we can say that evolution is related to classification of living beings...
(b) we not saw the dinosaurs but we know that in past years they are existed ....how we known this?
due to fossils (bones of species after death) we known that.....
in one village we found out that fossils of dinosaur, then we collected and put them in a order..... in meusem.....
we known that in past years there are dinosaurs by this evidence...
by this we can conclude that fossils are the solid evidences to study evolution of life.....
hope it help you.....
