Identify three weaknesses of naturalistic observation. 1.) Without various groups, it is hard to determine cause and effect. 2.) It is hard to make sure the researcher does not accidentally influence the results since it is hard for people not to notice when being observed. 3.)

Genetic drift occurs due to random fluctuations in the frequency of alleles (versions of a gene) in a population. These fluctuations can happen for a variety of reasons, such as chance events like a natural disaster (e.g. volcanic eruptions), which kills a significant proportion of a population and disproportionately affects certain individuals.
