Which is not a feature of neodrawinism ?

Options

A. Rapid multiplication
B. Struggle for existence
C. Natural selection
D. Inheritance of acquired characters

Answer

To determine which feature is not a part of neo-Darwinism, we need to understand the key concepts associated with this theory. Neo-Darwinism is an extension of Darwin's theory of evolution, incorporating Mendelian genetics. Here’s a step-by-step breakdown of the features of neo-Darwinism:

### Step 1: Understand Neo-Darwinism
Neo-Darwinism combines Darwin's theory of natural selection with Mendelian genetics. It emphasizes that evolution occurs through the gradual accumulation of small genetic changes.

### Step 2: Identify Key Features of Neo-Darwinism
1. **Natural Selection**: This is a core component, where organisms that are better adapted to their environment tend to survive and reproduce.
2. **Genetic Inheritance**: Traits are passed from one generation to the next through genes.
3. **Struggle for Existence**: Organisms compete for limited resources, leading to survival of the fittest.
4. **Rapid Multiplication**: This refers to the ability of organisms to reproduce quickly, leading to a larger population.

### Step 3: Analyze the Options
Now, let’s analyze the options provided in the question:
- **Option 1: Rapid Multiplication** - This is a feature of neo-Darwinism as it relates to population dynamics.
- **Option 2: Struggle for Existence** - This is a fundamental concept in neo-Darwinism.
- **Option 3: Natural Selection** - This is a key principle of neo-Darwinism.
- **Option 4: Inheritance of Acquired Characteristics** - This concept, proposed by Lamarck, states that traits acquired during an organism's lifetime can be passed to offspring. This is **not** a feature of neo-Darwinism.

### Step 4: Conclusion
The feature that is **not** a part of neo-Darwinism is the **inheritance of acquired characteristics**. Therefore, the correct answer is Option 4.
