According to Hugo de vires speciaton due to mutation is also known as 'Saltation which means

Options

A. single step variation
B. Variations at regular intervals
C. Single step large mutation
D. Huge change due to Natural selection

Answer

### Step-by-Step Text Solution:

1. **Understanding the Concept of Speciation**:
- Speciation refers to the process through which new species arise. This can occur through various mechanisms, one of which is mutation.

2. **Introduction to Hugo de Vries**:
- Hugo de Vries was a Dutch botanist and geneticist known for his work on mutation and its role in evolution. He proposed that mutations can lead to the formation of new species.

3. **Definition of Saltation**:
- De Vries introduced the term "saltation" to describe speciation that occurs through significant mutations. Saltation implies that the changes are not gradual but rather occur in large, sudden leaps.

4. **Characteristics of Saltation**:
- In saltation, a single large mutation can result in the immediate formation of a new species, rather than the gradual changes proposed by Darwin's theory of evolution.

5. **Examples of Saltation**:
- An example of saltation can be seen in the evolution of placental mammals and marsupials, where significant genetic changes led to the emergence of distinct groups.

6. **Conclusion**:
- According to Hugo de Vries, speciation due to mutation is known as saltation, which means the formation of new species through large, sudden mutations rather than gradual changes.
