Question

a. Give 3 important features of fossils which have helped in the study of evolution.

b. How does taxonomy support evolution?

Answer 1

Evidences of fossils are called paleantological evidences.
Fossils are remains of hard parts of life forms found in rocks

Diff aged rock sediments contain fossils of diff life forms who probably died during the formation of the particular segment
Some of them appear similar to modern organisms

*A study of fossils in diff sedimentary layers indicates the geological time period in which they existed.

*The study showed that life forms varied over time to time and certain life forms are restricted to certain geological time spans

Answer 2

Answer:

Taxonomy such as evolutionary taxonomy helps to classify organisms on the basis of ancestral relationships. It also gives the detail of evolutionary changes as well as progenitor-descendant relationship. The system of taxonomy is based on evolutionary and genetic differences
