What is Speciation? Explain the Process of speciation.

1.	What is Speciation? Explain the Process of speciation.
Answer» Speciation: It is an event that splits a population into two independent species which cannot reproduce among them. • Process of speciation- Genetic drift: It occurs due to changes in the frequencies of particular genes by chance alone. e.g. If a hurricane strikes the mainland, and bananas with beetle eggs on them are washed away to an island. This is called a genetic drift. natural selection: These are the variations caused in individuals due to natural selection which lead to the formation of a new species. e.g. If the ecological conditions are slightly different on the island as compared to the mainland, it leads to a change in the morphology and food preferences in the organisms over the course of generations. splitting of population: A population splits into different subpopulations due to geographical isolation that leads to the formation of a new species.
