Mention three important features of fossils which help in the study of evolution.

(a) Fossils represent modes of preservation of ancient species. (b) Fossils help in establishing evolutionary traits among organisms and their ancestors. (c) Fossils help in establishing the time period in which organisms lived.

Three important features of fossils which help in the study of evolution are : 

(i) Fossils represent modes of preservation of ancient species. 

(ii) Fossils help in establishing evolutionary traits among organisms and their ancestors. 

(iii) Their physical structure helps us provide a link between two different species of Organisms.

• Fossils are the preserved ancient species 
• Fossils help determine evolutionary differences between organisms and their ancestors.
• Fossils determine the living period of specific species.
