Explanation:
Answer:
Speciation
1. It is an event that splits a population into two independent species which cannot reproduce among them.
2. 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.
3. Process of speciation - 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.
4. Process of speciation - splitting of population: A population splits into different sub-populations due to geographical isolation that leads to the formation of a new species.
