Question

According to Hugo de Vries:

• A. Mutations appear with prior clues
• B. Mutations are raw material for evolutions
• C. Mutations lead to increased complexity
• D. Mutations have no role in species formation and hence known as saltation

Answer 1

The correct option is B Mutations are raw material for evolutions

Huge de Vries believed that mutation causes evolution and not the minor heritable variations. Mutations appear all of a sudden and are raw materials for evolution. They are random and directionless, so cannot always lead to increased complexity. It causes species formation and hence known as saltation(single step large mutation).
