The CCC model emphasizes the need to consider the quantity and placement of various life forms on the Earth within Creation Week. In the case of human beginnings, Genesis is quite clear that only one man (Adam) and only one woman (Eve) existed when the week ended. Furthermore, they were commanded to "be fruitful and increase in number; fill the earth and subdue it" (Gen. 1:28). This introduces the need for time. The fact that it took humans many, many generations and years to fulfill that command has important geological considerations.
In the same way, God earlier spoke of the need for sea creatures to "be fruitful and increase in number and fill the water in the seas, and let the birds increase on the earth" (Gen. 1:22). This plainly tells us that God did not originally create large populations of sea life and birds. It strongly implies restriction in number and location that required time for them to fill their ecological niches. While a restriction in numbers is not specifically mentioned of land animals, we know by observation today—long after the redistribution of the animals after the Flood—that few animals have universal distribution.
These built-in ranges of habitats resulted in limited mixtures of flora and fauna in each environment or ecological niche. These restricted habitats play important roles in determining what life forms are available for preservation as fossils in each area at any given time since Creation Week.
