Darwinism explains all the following except

Options

A. offspring with better raits that overcome competition are best suited for the enviorment
B. variations may not be inherited from parents t offspring through genes.
C. within each species, there are variations
D. organisms tend to produce more number of offspring than can survive.

Explanation

To solve the question "Darwinism explains all the following except," we need to analyze the statements provided and identify which one does not align with Darwin's theory of natural selection.

### Step-by-Step Solution:

1. **Understand Darwinism**: Darwinism refers to the theory of evolution proposed by Charles Darwin, primarily based on the concept of natural selection. This theory explains how species evolve over time through the survival and reproduction of individuals with favorable traits.

2. **Identify Key Concepts**:
- **Variations**: Within any population, individuals exhibit variations.
- **Natural Selection**: Some variations are beneficial and enhance survival and reproduction.
- **Survival of the Fittest**: Those individuals that are better adapted to their environment are more likely to survive and reproduce.

3. **Analyze Each Statement**:
- **Statement 1**: "Offspring with better traits that overcome competition are best suited for the environment."
- This aligns with Darwinism as it reflects the idea of natural selection.
- **Statement 2**: "Variations may or may not be inherited from parents to offspring through the genes."
- This statement contradicts Darwinism because Darwin's theory emphasizes that beneficial variations must be inheritable to affect evolution.
- **Statement 3**: "Within each species there are variations."
- This is a fundamental aspect of Darwin's theory.
- **Statement 4**: "Organisms tend to produce more number of offspring that can survive."
- This is also consistent with Darwinism, as it reflects the idea of overproduction leading to competition.

4. **Conclusion**: The statement that does not align with Darwinism is **Statement 2**: "Variations may or may not be inherited from parents to offspring through the genes." This is incorrect because Darwinism is based on the idea that only inheritable variations can contribute to evolution.

### Final Answer:
Darwinism explains all the following except: **Variations may or may not be inherited from parents to offspring through the genes.**
