Fossils are the remains of the organisms that once existed on earth, t.e., they are the preserve traces of living organisms. They provide evidence of evolution by revealing the characteristic of the past Organisms and the changes that have occurred in these organisms to give rise to the present organisms.

Two ways of determining age of fossils are:

➊ Relative method-fossils closer to the surface are more recent.

➋ Dating-finding the ratio of different isotopes of the same element.
