Geologic Time – Period prior to humans. 4.6 billion to 3 million years ago. (See "prehistoric periods" for more detail into this.) Primatomorphid Era – Period prior to the existence of Primatomorpha, before this point, no even distantly human-like creatures would exist. Primate Era – Period prior to the existence of Primates. History of. the Earth The Earth's history is recorded in the rocks of the crust. Scientists used an assumption called uniformitarianism in order to relate what we know about present-day processes to past events - the present is the key to the past. Uniformitarianism states that the natural laws we know today have been constant over the geoiogic past. Earth's Early …Understanding these processes is pivotal in groundwater resources management, geological carbon ... first-order gradient optimality with a tolerance of 10 −10 or on loss function value or parameters changes with a tolerance of 10 −12.
