The process of the evolution of a new species happens mainly because of natural selection.

New species can emerge only if there is a change in the ______.
surrounding environment
reduction of variation in a population
gene pool
migration of the population
The process of the evolution of a new species happens mainly because of natural selection. This is when a mutation in the gene causes a change in the physical characteristics that allows better survival; therefore, that physical characteristic is carried on to the next generations.
