1. These four factors can effect ways evolution occur:
<span>1.) Mutation 
2.) selection
3.) Gene Flow
4.) Genetic Drift 
2.  </span>In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes by means of natural or artificial controlling factors. 
In population genetics, gene flow is the transfer of alleles or genes from one population to another.
<span>Genetic drift  is the change in the frequency of a gene variant in a population due to random sampling of organisms. </span>
