Select the correct statement from the following.

Options

A. Fitness is the end result of the ability to adapt and get selected by nature.
B. Natural selection and genetic variation are two main key point of Darwinian Theory of evolution.
C. Adaptive ability is always inherited
D. Placental wolf and Tasmanian wolf are example of homology.

Answer

To solve the question "Select the correct statement from the following," we will evaluate each of the provided statements one by one.

### Step-by-Step Solution:

1. **Evaluate the First Statement:**
- Statement: "Fitness is the end result of the ability to adapt and get selected by nature."
- Analysis: This statement aligns with Darwin's theory of natural selection. It suggests that organisms that can adapt to their environment are more likely to survive and reproduce, leading to the concept of "survival of the fittest."
- Conclusion: This statement is **correct**.

2. **Evaluate the Second Statement:**
- Statement: "Natural selection and genetic variation are the two main key points of the Darwin theory of evolution."
- Analysis: While natural selection is indeed a key point of Darwin's theory, genetic variation is not explicitly mentioned as a key point in the context of Darwin's original theory. It is more of a modern addition to the understanding of evolution.
- Conclusion: This statement is **incorrect**.

3. **Evaluate the Third Statement:**
- Statement: "Adaptive ability is always inherited."
- Analysis: This statement is misleading. While some traits that confer adaptive advantages can be inherited, not all adaptive abilities are genetic. Adaptations can occur in response to environmental changes, and these changes may not be passed down to the next generation.
- Conclusion: This statement is **incorrect**.

4. **Evaluate the Fourth Statement:**
- Statement: "Placental Wolf and Tasmanian Wolf are the examples of Homology."
- Analysis: This statement is incorrect because the Placental Wolf (a type of placental mammal) and the Tasmanian Wolf (or Tasmanian Tiger, a marsupial) are examples of convergent evolution, not homology. They evolved similar traits independently due to similar environmental pressures.
- Conclusion: This statement is **incorrect**.

### Final Conclusion:
The only correct statement is the **first statement**: "Fitness is the end result of the ability to adapt and get selected by nature."
