Which of the following is correct ?

Options

A. Lion and leopard show convergent evolution
B. Camouflage is shown by Biston betularia.
C. Natural selection is responsible for extintion of Dinosaurs.
D. Homo habilis and Homo erectus are clossely retated.

Answer

To determine which statement is correct among the given options, we will analyze each statement step by step.

### Step 1: Analyze the first statement
**Statement:** Lion and Leopard show convergent evolution.
**Analysis:**
- Convergent evolution occurs when different species develop similar traits or adaptations due to similar environmental pressures, despite having different ancestral origins.
- Lions and leopards are both felids and share a common ancestor, but they have diverged into different species with distinct traits. Therefore, this statement is incorrect.

### Step 2: Analyze the second statement
**Statement:** Camouflage is shown by Biston-Betularia.
**Analysis:**
- Biston-Betularia, commonly known as the peppered moth, is a classic example of natural selection and camouflage.
- During the Industrial Revolution, the coloration of these moths changed from light to dark due to pollution, which helped them blend into their environment and avoid predation. This statement is correct.

### Step 3: Analyze the third statement
**Statement:** Natural selection is responsible for the extinction of dinosaurs.
**Analysis:**
- While natural selection plays a role in evolution, the extinction of dinosaurs is primarily attributed to catastrophic events, such as the asteroid impact and volcanic activity, rather than natural selection alone. Therefore, this statement is incorrect.

### Step 4: Analyze the fourth statement
**Statement:** Homo habilis and Homo erectus are closely related.
**Analysis:**
- Homo habilis and Homo erectus are indeed part of the human evolutionary lineage, but they are distinct species with differences in their physical characteristics and time periods. While they share a common ancestor, they are not as closely related as the statement implies. Therefore, this statement is also incorrect.

### Conclusion
After analyzing all the statements, we find that the only correct statement is the second one: **Camouflage is shown by Biston-Betularia.**
