List two evidences of mutation theory of evolution.

Explanation

**Step-by-Step Text Solution:**

1. **Introduction to Mutation Theory of Evolution:**
- The mutation theory of evolution was proposed by Hugo de Vries. It suggests that small changes in the genetic material (DNA) can lead to variations in traits, which can be passed from parents to offspring over generations.

2. **Mechanism of Mutation:**
- Mutations occur due to errors in DNA replication or external factors that cause changes in the base pairs of DNA. These changes can result in new traits or characteristics in organisms.
