Answer

**Step-by-Step Solution:**

1. **Introduction to Homo erectus:**
- Homo erectus is an early human species that lived approximately 2 million years ago. They are often referred to as cave dwellers due to their habitat.

2. **Physical Characteristics of Homo erectus:**
- They had a cranial capacity of about 900 cc, which is relatively smaller compared to later human species.
- A notable physical feature is the absence of a chin, which distinguishes them from more advanced human species.
- Their skull structure was prognathous, meaning they had a protruding jaw.

3. **Introduction to Cro-Magnon Man:**
- Cro-Magnon Man is considered a direct ancestor of modern humans and lived later than Homo erectus.
- They are known for their advanced behaviors and creativity.

4. **Physical Characteristics of Cro-Magnon Man:**
- Cro-Magnon had a larger cranial capacity of about 1650 cc, indicating a more developed brain.
- They had a well-defined chin, which is a significant difference from Homo erectus.
- Their skull structure was orthognathous, meaning they had a more flat and less protruding jaw.

5. **Cultural and Technological Differences:**
- Homo erectus primarily created simple stone tools, while Cro-Magnon Man developed more sophisticated tools and weapons.
- Cro-Magnon Man is also known for their artistic abilities, such as cave paintings, which were not characteristic of Homo erectus.

6. **Conclusion:**
- In summary, Homo erectus differed from Cro-Magnon Man in several key aspects: cranial capacity, physical features (presence of chin and jaw structure), and cultural advancements (tool-making and artistic expression).
