Homo erectus different from Cro-magnon man in having

Options

A. Jaws protruding out
B. Tool making
C. Sloping jaws
D. Arts and paintings

Answer

**Step-by-Step Solution:**

1. **Identify the Species**: First, we need to clarify the two species in question: Homo erectus and Cro-Magnon man. Homo erectus existed approximately 1.9 million to 110,000 years ago, while Cro-Magnon man, a type of early modern human, lived around 40,000 years ago.

2. **Examine Physical Characteristics**: One of the key differences between these two species lies in their physical characteristics, particularly the structure of their jaws.

3. **Analyze Jaw Structure**: Homo erectus had a more pronounced jaw structure, characterized by protruding jaws. This means that their jaws extended outward more than those of Cro-Magnon man.

4. **Compare with Cro-Magnon Man**: In contrast, Cro-Magnon man had a more modern jaw structure, which was straighter and less protruding. This change in jaw structure is a significant evolutionary trait that distinguishes the two species.

5. **Conclusion**: Based on the differences in jaw structure, we can conclude that the primary distinction between Homo erectus and Cro-Magnon man is that Homo erectus had protruding jaws, while Cro-Magnon man had straighter jaws.

**Final Answer**: Homo erectus is different from Cro-Magnon man in having protruding jaws.
