Explain the salient features of Hugo de Vries theory of mutation. How is Darwin's theory of natural selection different from it?

Explanation

### Step-by-Step Solution:

1. **Introduction to Hugo de Vries' Theory of Mutation**:
- Hugo de Vries proposed his theory of mutation in 1901. He introduced the concept that mutations are the primary driving force behind evolution.

2. **Key Features of Hugo de Vries' Theory**:
- **Sudden Changes**: De Vries argued that mutations occur suddenly rather than gradually. This means that new traits can appear abruptly in a population.
- **Discontinuous Evolution**: He suggested that evolution is not a smooth, gradual process but rather a series of jerky changes. This implies that species can change significantly in a short period.
