Question

What is meant by speciation"? State the various factors which could lead to the formation of new species."

Answer 1

Answer:

The formation of a new species by evolution or any genetic modification of the previously existing species in a population is called Speciation. ... Geographic isolation: Rise of mountain, continental drifts, river flow change and other topographical changes cause isolation of population resulting inspeciation.

Answer 2

Mutation & Genetic Drift are Factors of Speciation

Explanation:

• Speciation is the formation of new species from the pre-existing population.

Factors responsible for speciation:

• Genetic drift

• Natural selection

• Geographical isolation

• Mutation

Geographical isolation cannot be a major factor in the speciation of a self pollinating plant species because physical barrier cannot be created in self-pollinating plants.
