Assertion: Neanderthal man is the intermediate between Ramapithecus and Homo erectus.
Reason: Neanderthal man, with brain sizeof 800 c.c., used hides to protect their body.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that Neanderthal man is the intermediate between Ramapithecus and Homo erectus. To evaluate this, we need to understand the timeline and evolutionary relationships of these species.

2. **Evaluating Ramapithecus**: Ramapithecus is an ancient primate believed to have lived around 15 million years ago. It is one of the earliest known ancestors in the human lineage and is more primitive compared to later hominids.

3. **Evaluating Homo erectus**: Homo erectus is a more recent species that lived approximately 1.5 million years ago. It is considered a direct ancestor of modern humans (Homo sapiens) and shows significant advancements in tool use and social behavior.

4. **Evaluating Neanderthal Man**: Neanderthal man lived much later, around 100,000 to 40,000 years ago. They are considered to be a separate branch of the human lineage, distinct from both Ramapithecus and Homo erectus.

5. **Conclusion on the Assertion**: Since Ramapithecus is much older than both Homo erectus and Neanderthal man, it is incorrect to state that Neanderthal man is an intermediate between Ramapithecus and Homo erectus. Therefore, the assertion is **false**.

6. **Understanding the Reason**: The reason states that Neanderthal man had a brain size of 800 c.c. and used hides to protect their body. While it is true that Neanderthals used hides, the stated brain size is inaccurate.

7. **Evaluating Brain Size**: The average cranial capacity of Neanderthal man is approximately 1400 c.c., which is larger than the 800 c.c. mentioned in the reason. The brain size of 800 c.c. is more representative of Homo erectus.

8. **Conclusion on the Reason**: Since the brain size given in the reason is incorrect, the reason is also **false**.

9. **Final Conclusion**: Both the assertion and the reason are false. Therefore, the correct answer is that both statements are incorrect.
