Question

Define speciation mention two factors causing speciation

Answer 1

Speciation is the process of generation of a new species from a pre-existing species by variations in DNA copying.

Factors that facilitate speciation are:

1. Natural Selection

2. Genetic Drift

3. Geographical isolation

Answer 2

Answer:

here your answer

Explanation:

Speciation occurs when two or more populations become so genetically distinct that they no longer interbreed with one another. There are multiple ways this canoccur. The natural waysspeciation can occur are allopatric, parapatric, and sympatric speciation.

Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations
