Long depression in Southwest Asia and East Africa caused by the movement of tectonic plates, largely beginning during the Oligocene Epoch. In Africa, it extends from Ethiopia southwest 1200 miles through the lake regions. Many of the early hominin discovery sites are in this valley system.

Laying partly curled on one's side with the legs and arms bent and held into the body.
Industry:Anthropology
Lateral and/or vertical movement of segments of the earth's crust. The continents and the ocean floors consist of tectonic plates that are moving relative to each other. On average, such movements are about 1 inch per year.

Lamarck's theory that evolution occurs as a result of an organism acquiring a change in form due to using or not using particular body parts during its lifetime and then passing the new trait on to its offspring. This is also referred to as the "use-disuse theory. "

Inorganic, naturally occurring materials consisting of specific elements. They are usually rocks with a characteristic crystalline structure and other identifiable physical traits. Quartz, talc, and ordinary table salt are examples of minerals.

Inheritance patterns which can be explained by simple rules of dominance and recessiveness of genes.
Industry:Anthropology
Increased health of individuals who are the result of negative assortative mating, or crossbreeding. This is due to the fact that when mates are from very different genetic lines they are more likely to have lower frequencies of homozygous recessive conditions. Subsequently, they are liable to be more viable. This phenomenon has also been referred to as hybrid vigor.

Incisor teeth that have a "scooped out" appearance on the tongue side. This pattern is characteristics of East Asian and Native American Populations today. It was also common among Homo erectus.

Identical twins. Twins that come from the same zygote and are, subsequently, the same genetically in terms of their nuclear DNA. Any differences between monozygotic twins later in life are mostly the result of environmental influences rather than genetic inheritance. Fraternal twins may look similar but are not genetically identical. Monozygotic twins may not share all of the same sequences of mitochondrial DNA. This is due to the fact that the mitochondria in a cell may have somewhat different versions of DNA, and the mitochondria can be dispersed unequally when a zygote fissions. Female monozygotic twins can also differ because of differences between them in X-chromosome inactivation. Subsequently, one female twin can have an X-linked condition such as muscular dystrophy and the other twin can be free of it.
