Depiction of the existence of life on earth in four dimensions

The subject structure consists of a base, a spine rising from the base, and a group of Earth planetary illustrations affixed at intervals along the height of the spine. Colors, symbols, text, texture, and artifacts on an illustration represent specified characteristics of biological forms and planetary conditions for one or more sites on the Earth at a given time, past, present or future. The intervals between the locations of the illustrations along the height of the spine represent time intervals in the existence of Earth. This overall presentation therefore displays biological and environmental information on a global platform as conditions change through time. The information specified is drawn from published research and recognized researchers and is also recorded in and retrievable from an associated database.
