The five major types of fronts (cold, warm, occluded, stationary and dry line phenomena) depend on the direction of the air mass's travel and its characteristics. While fossil evidence alone does not prove that all life forms are related by common ancestry, the fossil record is consistent with (and highly suggestive of) that conclusion. MISCONCEPTION: Evolution is a theory about the origin of life. Most organisms decompose before this can happen.
