Fossil age can determine organism changes related to the time scale.
(true or false)

True,

Reason -

Fossil records are very important to study the early forms of life and their development with course of time. The gaps is fossil records signifies that the species belonging to these gaps must be made of unstable or easily decomposable material and thus they do not exists today. Fossils also provide us evolutionary history of organisms for instance, some paleontologists believe that whales evolved from land-dwelling animals, like wise evolution of human being is from their nearest ancestors i.e apes.

Thus, Fossil age can determine organism changes related to the time scale
