Fossils

Analogous Organs

Correct Answer:

Fossils

Explanation:

The correct answer is Option (3)- Fossils

The study of fossils is called Palaeontology (also spelt as Paleontology). The definition of palaeontology is that it is the scientific study of prehistoric life on Earth, especially the species that are extinct, and it focuses on the study of fossils by using a variety of chemical, physical, and biological analytics techniques.

The study of fossils includes the determination of the evolution and prehistoric structure of extinct plants, animals, single-celled living organisms, fungi, and bacteria, by analyzing the paleontological evidence from the impressions on the deposited rock strata in which the remains of the species are found. An interesting fact is that the study of fossils of dinosaurs is also called palaeontology which belongs to the branch of geology. 

Fossils are the geological remains and scientific traces of organisms in the past excavated from the soil. The individual study of fossils is beneficial because the fossils or skeletons contain information about the life of an organism and its environment. An example of paleontological evidence is the presence of rings on the surface of an oyster which represents the number of years of its life. From the shell of this same oyster, paleontologists can tell the climate and conditions in which it developed.

Resin is a sticky substance that drops down the tree and hardens, and sometimes it also traps air bubbles, insects, lizards, or other small organisms. Hence, paleontologists also call this ‘fossil resin’ because it contains the paleontological evidence of ancient substances and can tell a lot about the conditions of the time it was formed.
