Question

Palaeontologists deal with____

• A. Embryological evidence
• B. Fossil evidence
• C. Vestigial organ
• D. All

Answer 1

The Correct Option is B

To solve the problem, we need to determine what palaeontologists primarily deal with. Palaeontology is the scientific study of prehistoric life forms based on fossilized remains and other evidence such as imprints or traces.

1. Understanding the Role of Palaeontologists:
Palaeontologists focus on studying fossils to understand the history of life on Earth. They analyze these fossils to reconstruct the anatomy, behavior, and evolution of ancient organisms. This field is closely related to geology and biology.

2. Evaluating the Options:
Let us evaluate each option provided:

1. Embryological evidence: While embryological evidence can provide insights into evolutionary relationships, it is not the primary focus of palaeontologists. Embryology deals with the development of embryos, which is a different field of study.
2. Fossil evidence: Fossils are the primary source of information for palaeontologists. By examining fossils, they can infer details about the organisms that lived in the past, their environments, and their evolutionary history. This is the correct answer.
3. Vestigial organ: Vestigial organs are remnants of structures that were functional in ancestral species but have lost their original function over time. While vestigial organs can be studied by biologists and evolutionary scientists, they are not the main focus of palaeontologists.
4. All: This option suggests that palaeontologists deal with all three categories. However, while fossils may sometimes reveal embryological or vestigial features, the primary focus is on fossil evidence.

3. Conclusion:
The primary focus of palaeontologists is fossil evidence. Therefore, the correct answer is:

Final Answer: (B) Fossil evidence
