Select the correct statement regarding mutation theory of evolution.
Select the correct statement regarding mutation theory of evolution.
This theory was proposed by Alfred Wallace
Variations are small directional changes
Single step large mutation is a cause of speciation
Large differences due to mutations arise gradually in a population

The concept of evolution through mutation was given by Hugo de vries.
$\rightarrow$ Mutations are sudden aberration/change that arise in the population thus they are discontinuous in nature.
$\rightarrow$ Large single step changes are called Saltation which lead to speciation.
