Why do we dig fossils and study them ?

Options

A. To find new fossils that have not yet been recorded.
B. Fossil finding gives occupation to scientist .
C. Fossils fill the gap in the evolutionary records of animals.
D. Fossil throw light on the evolution of animals of the past.

Answer

### Step-by-Step Solution:

1. **Definition of Fossils**:
- Fossils are the preserved remains or traces of plants and animals that lived in the past. They are typically found in sedimentary rock and can include bones, shells, imprints, and other biological materials.

2. **Location of Fossils**:
- Fossils are usually buried deep under the soil. The depth at which a fossil is found can indicate its age; generally, the deeper the fossil, the older it is.

3. **Importance of Digging Fossils**:
- Digging for fossils allows scientists to uncover these ancient remains, which provide valuable information about the history of life on Earth.

4. **Understanding Evolution**:
- By studying fossils, scientists can learn about the evolution of species. Fossils provide evidence of how different organisms have changed over millions of years, helping to map out the evolutionary tree of life.

5. **Research and Knowledge**:
- Fossils help fill gaps in our understanding of evolutionary history. They provide insights into the physical characteristics, behaviors, and environments of extinct species.

6. **Conclusion**:
- The primary reason for digging and studying fossils is to gain insights into the evolution of past life forms and understand how they have adapted and changed over time.
