The idea of mutations was brought forth by

Options

A. Hugo de vries, who worked on evening primrose
B. Gregor Mendel, who worked on pisum sativum
C. Hardy Weinberg, who worked on allele frequencies in a population
D. Charles Darwin, who observed a wide variety of organisms during sea voyage

Answer

**Step-by-Step Solution:**

1. **Understanding the Concept of Mutations**:
- Mutations refer to changes in the genetic material (DNA) of an organism. These changes can occur in various forms and can be passed down to subsequent generations.

2. **Identifying Key Contributors to the Concept of Mutations**:
- The question asks who brought forth the idea of mutations. We need to analyze the options provided:
- **Yugo de Vries**: A Dutch botanist known for his work on plant species and mutations.
- **Gregor Mendel**: Known for his foundational work in genetics using pea plants (Pisum sativum).
- **Hardy Weinberg**: Known for the Hardy-Weinberg principle related to allele frequencies in populations.
- **Charles Darwin**: Known for his observations and theories on evolution and natural selection.

3. **Analyzing Yugo de Vries's Contribution**:
- Yugo de Vries studied evening primrose and observed that while offspring retained some genetic information from their parents, there were also significant changes. He concluded that these changes were mutations, which he described as a fundamental aspect of evolution.

4. **Conclusion**:
- Based on the analysis, Yugo de Vries is credited with the idea of mutations and is often referred to as the "father of mutation." Therefore, the correct answer to the question is Yugo de Vries.

**Final Answer**: The idea of mutations was brought forth by Yugo de Vries.
