➢ Any preserved remains, impression, or trace of organisms that lived in the past is called fossil. Examples include bones, shells, exoskeletons, stone imprints of animals, etc.

Importance of fossils as proof as evolution:

The time of death of a plant or animal can be calculated by measuring the radioactivity of C-14 and ratio of C-14 to C-12 (non-radioactive carbon) present in their body of the fossil organism. By determining the age fossil. This called carbon dating.

Once the age of fossil been determined, it is easy to gather the information about other past lived organisms. It can be concluded that vertebrates have been slowly originated from invertebrates.

Answer 2

Answer:

Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.
