One thing that is not similar in great apes and man is

Options

A. Posture
B. DNA content
C. Protein homology
D. Branding pattern of chromosome

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a characteristic that is not similar between great apes and humans. To answer this, we need to identify the differences between the two.

2. **Identifying Similarities**: First, we acknowledge that there are many similarities between great apes and humans, such as genetic makeup, protein homology, and chromosomal patterns. These similarities indicate a close evolutionary relationship.

3. **Focusing on Differences**: Since the question specifically asks for something that is not similar, we need to look for a characteristic that distinguishes humans from great apes.

4. **Analyzing Posture and Locomotion**: One of the most notable differences between great apes and humans is their mode of locomotion. Great apes typically walk on all fours (quadrupedal locomotion), using their arms and legs for movement. In contrast, humans are bipedal, meaning they walk upright on two legs.

5. **Conclusion**: Therefore, the primary characteristic that is not similar between great apes and humans is their posture and method of walking. Humans have an erect posture, while great apes do not.

**Final Answer**: The one thing that is not similar in great apes and man is their posture and method of locomotion; humans walk upright (bipedal), while great apes walk on all fours (quadrupedal).
