Answer:
Genetic Mutation
Explanation:
Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time.
There are a number of different mechanisms that may drive speciation.
Two of them to point out here.
1. natural selection
2. genetic drift
genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.
Explanation:
Both Darwin and Mendel proposed their theory at the same time but they never communicated with each other. They both explained the population and studied the variation between them and in them.
The variation within a population could be of two types: the discontinuous traits and the quantitative trait.
A discrete trait refers to a trait that is usually controlled by only one gene that is only two alleles or two variants are observed in the population whereas the quantitative trait is a trait that can be determined by more than one gene like the variation in height.
