The evolution of a new species from an existing species is ____
A
natural selection
B
isolation
C
speciation
D
genetic variation
Explanation: 

Detailed explanation-1: -New species arise through a process called speciation. In speciation, an ancestral species splits into two or more descendant species that are genetically different from one another and can no longer interbreed. Darwin envisioned speciation as a branching event.

Detailed explanation-2: -Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms.

Detailed explanation-3: -Speciation: The evolutionary processes through which new species arise from existing species. Species: In sexually reproducing organisms, species consist of individuals that can interbreed with each other.

Detailed explanation-4: -A species is a group of organisms with similar characteristics and can interbreed to give fertile offspring. Speciation is an evolutionary process of the formation of new and distinct species. The species evolve by genetic modification.
