Genetic Drift vs. Gene Flow vs. Natural Selection

WebGenetic drift refers to random fluctuations in allele frequencies in small populations, while taxonomy is the science of naming, describing, and classifying organisms. Speciation is the process by which new species evolve from existing species through the accumulation of genetic and phenotypic differences over time. 4.
