Explain the terms
(i) Speciation (ii) Natural selection

Explanation

a) Speciation is the formation of new species in the course of evolution.
The factors that could lead to speciation are:
i] Natural selection
ii] Geographic isolation
iii] Mutation
iv] Genetic drift
b] Natural Selection: It is a process that occurs in nature by which organisms that are well adapted to a particular environment survive better and produce more offsprings than the ones that are not. This results in the elimination of the less adapted ones in the succeeding generations.
