Day-Age creationism - A type of Old Earth creationism, is an interpretation of the creation accounts found in Genesis. It holds that the six days referred to in the Genesis account of creation are not ordinary 24-hour days, but rather are much longer periods (of thousands or millions of years). The Genesis account is then interpreted as an account of the process of cosmic evolution, providing a broad base on which any number of theories and interpretations are built.
Direct fitness - A measure of the number of genes passed on to the next generation relative to other genetic contributions; individuals maximize their fitness by having as many offspring as possible that live to reproduce (and contribute their genes to the next generation).
DNA - Deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
Dominant allele - A particular version of a gene that is always expressed, no matter what other copy of the gene is possessed by the organism. An example of a dominant allele is the allele for black-colored hair in cattle.
