Common origin of man and chimpanzee is best shows by

Options

A. Binocular vision
B. Homology in chromosomes
C. Dental formula
D. Cranial capacity

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which evidence best demonstrates the common origin of man and chimpanzee. The options provided are binocular vision, homology in chromosomes, dental formula, and cranial capacity.

2. **Analyzing the Options**:
- **Binocular Vision**: While both humans and chimpanzees have binocular vision, this trait is not unique to them and does not specifically indicate a common ancestry.
- **Homology in Chromosomes**: This refers to the similarities in the chromosome structure and number between species. Humans have 46 chromosomes, while chimpanzees have 48. Studies have shown that the chromosomal patterns are similar, indicating a common ancestor.
- **Dental Formula**: The dental formula refers to the arrangement of teeth. While there are similarities, they are not as strong as chromosomal evidence in demonstrating common ancestry.
- **Cranial Capacity**: This refers to the volume of the skull. Although humans have a larger cranial capacity compared to chimpanzees, this does not provide direct evidence of a common origin.

3. **Conclusion**: Based on the analysis, the best evidence for the common origin of man and chimpanzee is the homology in chromosomes. This is supported by scientific studies that have shown similarities in chromosomal patterns, indicating that both species evolved from a common ancestor.

4. **Final Answer**: The common origin of man and chimpanzee is best shown by homology in chromosomes.
