How Mammals Inherited the Earth
One of the mysteries of geology is why the earliest mammal fossils found after the disappearance of the dinosaurs were unlike today's most familiar mammals. Or, to put it another way, why did the exit of the dinosaurs not immediately open the door for the modern types of mammals to take over the dinosaurs' previous ecological niches?
This geologic mystery shows small mammals living side-by-side with the dinosaurs, but the mammals we most associate with ourselves (primates, hoofed animals, etc.) do not immediately appear after the demise of the dinosaurs. What is a possible reason for this, biblically speaking?
The major divisions of living mammals — placentals, marsupials and monotremes — do indeed appear along with dinosaur fossils. However, after the disappearance of the dinosaurs, it took awhile for the ancestors of many of todays most prominent mammal groups to flourish. The question is: "Why?" A non-evolutionary answer is based upon the simple principle of the food chain and the original placement of land life "in the beginning."
The Creation/Curse/Catastrophe (CCC) geologic model relies heavily upon the premise that life was not created uniformly upon the Earth. Rather, various groupings of life forms or ecologies were created in selective locations (creation centers). The stratigraphic fossil sequences of each local area give us good indications of how life forms changed sequentially within each region. The changes were due to a number of reasons: God's make-up of the original placement of life in each region "in the beginning;" the ecological change as new varieties within each created "kind" appear; and migration of new life forms from adjoining "creation centers" modifying the local food chain.
Life feeds on specific food sources. Complex food chains include "simple" life forms and also the most "advanced."
The CCC model postulates a complex geologic history developing after the Curse on the Earth due to man's original transgression. The dinosaurs' worldwide ecologies were located near the Earth's seas. Their food sources (ferns, conifers, etc.) were unlike the diet (angiosperms) of the mammals which were located on the stable inland shield areas of the continents. As the angiosperm vegetation of the mammals migrated from their creation centers to the outer realms of the dinosaurs, the result was a radical change in the plant life and hence the food source of most of the dinosaurs.
The earliest angiosperms to invade the dinosaur realm consisted of such trees as the magnolia, fig, sassafras, popular, and later the beeches, birches, maples, oaks, walnuts, etc. and various shrubs. The fossil mammals found immediately after the disappearance of the dinosaurs were unlike those of today. They were survivors of the radical vegetation change that helped doom the dinosaurs. Modern-type mammals came later onto the scene. Why?
The answer seems to rely heavily upon the migration and new varieties of the grasses from the inland creation centers. The arrival and later flourishing of the grasses paved the way for the grass-eating mammals familiar to us today. This later maturing of the flora food chain after the demise of the dinosaurs provides an explanation for the subsequent appearance of the modern-type mammals which require abundant and specific grasses within their food chain.
