Progressively changing zones of degree difference in frequency of a trait with movement from one region to another. The gradual decrease in frequency of the B blood allele going west in Europe is an example of such a gradation or clinal distribution. See discontinuous distribution.

Prominent projecting bony bars or brow ridges above the eyes. This trait was characteristic of Homo erectus and some other early humans.
Industry:Anthropology
Potentially, a chronometric dating method based on the fact that obsidian, or volcanic glass, progressively develops a thin chemically altered outer layer due to the absorption of water. The thickness of this hydration layer is directly proportional to the amount of time since the rock was formed or since a fresh surface was exposed to the elements. Since the rate of hydration varies between samples from different volcanic sources, this technique could arguably be considered relative rather than chronometric.
Industry:Anthropology
Permanently frozen soil. This is a common condition above the Arctic Circle and in other similarly cold environments.
Industry:Anthropology
Oxygen deprivation. This condition can occur at high altitude. Symptoms include a reduced ability to do work, fatigue, dizziness, nausea, and an inability to effectively perform memory intensive tasks.

In very high mountain areas, hypoxia can cause pulmonary edema and/or cerebral edema, both of which are life-threatening conditions that are aspects of what is often referred to as acute mountain sickness.
