Which one of the following is closest relative of Man?

Options

A. Gibbons
B. Chimpanzees
C. Orangutans
D. Gorillas

Answer

To determine which of the given options is the closest relative of man, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify the closest relative of humans among the given options: chimpanzees, orangutans, and gorillas.

2. **Review Primate Classification**: Humans belong to the order Primates. Within this order, there are different families, and one of the most relevant families is Hominidae, which includes humans and their closest relatives.

3. **Identify the Family**: In the family Hominidae, we have several genera, including Homo (which includes modern humans, Homo sapiens) and Pan (which includes chimpanzees).

4. **Compare the Options**:
- **Chimpanzees (Pan)**: They are in the same family (Hominidae) as humans and share a common ancestor.
- **Gorillas (Gorilla)**: They are also in the Hominidae family but are more distantly related to humans than chimpanzees.
- **Orangutans (Pongo)**: They are in the same family but are the most distantly related compared to chimpanzees and gorillas.

5. **Conclude the Closest Relative**: Based on the classification and evolutionary history, chimpanzees are the closest relatives to humans. This is supported by genetic studies which show that humans and chimpanzees share about 98-99% of their DNA.

6. **Final Answer**: Therefore, the correct answer is **chimpanzees**.
