Question

2). Define fossil. Explain importance of fossils as proof of evolution.​

Answer 1

Explanation:

Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.

Answer 2

$\huge\red{ꫝꫀꪶꪶꪮ}$

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.
