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. WebI'm investigating and learning more about how natural selection and genetic drift produce changes in species over time, and how those changes influence the environment. I'm exploring how adaptation is affected by the environment, how genetic mutations can affect species, and the importance of genetic diversity in a species' survival.
