Wilderness is generally defined as areas that have not been significantly modified by human activity. A latitudinal band of the surface with similar climatic attributes forms a climate region.
Species that were unable to adapt to the changing environment and competition from other life forms became extinct. Cells within colonies became increasingly specialized, resulting in true multicellular organisms.
Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated way. The structure and composition is determined by various environmental factors that are interrelated.
The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes.These currents help to moderate the differences in temperature between winter and summer in the temperate zones.
However, not every definition of life considers all of these properties to be essential. Human-made analogs of life may also be considered to be life. The fossil record retains evidence of many of these older species.
Wilderness areas can be found in preserves, estates, farms, conservation preserves, ranches, national forests, national parks and even in urban areas along rivers, gulches or otherwise undeveloped areas.
