selecting a problem-drinking partner is known as “nonrandom partner selection” (Egendorf 20). Further research has found that alcoholics and problem drinkers are likely to marry partners in the same condition which can increase the adverse outcomes of offspring by genetic and environmental risk. The genetic risk is that the offspring can inherit a genetic predisposition towards alcoholism through both the maternal and paternal sides of the family. The environmental risk is increased when two alcoholic

Darwin’s theory of natural selection is not supported by the geological or fossil record‚ since there have been little to no remains of intermediate species found in fossils. Darwin explains this by using the imperfection of the geological record‚ as changes in land over time means that species will often not be preserved in a way that can be studied by scientists. He also references Charles Lyell’s Principles of Geology‚ which states that the earth’s surface is constantly changing‚ as evidenced
