Question

State the mutation theory ? What are two main points which make it different from darwin theory ​

Answer 1

Explanation:

Mutations are random and directionless while Darwin's variations are small and directional. According to Darwin evolution is gradual while Hugo de Vries believed that mutation caused species formation and hence known as saltation (single step large mutation).

Answer 2

Explanation:

Answer:

The mutation theory differs from Darwin's theory in the nature of the variation

• Continuous variations or fluctuations are the raw materials for the formation of new species in Darwin's theory of natural selection,

• but in De Vries theory, discontinuous variations or mutations are the raw materials.

• Darwins theory stated that evolution is a gradual process while De Vries stated that the process is sudden.
