Define relative dating of fossils
This pattern arises when species that appear on few islands occur only on the islands with the most species, while only the most widespread species are found on the islands with few species (Wright et al., 1998).
The nested subset pattern arises because species differ in their distributions across space.
If the geologic column truly represents a series of closely spaced catastrophic burial events instead of long ages of time, how can this feature be explained?
Certainly this seems like a difficult and rather mysterious problem for those, like myself, who might think to question the long age notion of the fossil record.
However, science is suppose to do just that - challenge ideas. Because often what seems obvious initially does not turn out to be true.
The scientific method is all about testing and retesting theories since no theory is ever proven by science.
If those specific habitats are not occupied by a particular kind of creature, it may not be preserved in the fossil record even though it is still alive and well in some other habitat.Since each of these layers seems so specialized it is easy to conclude that one type of creature gave rise to the next type of creature over the course of whatever time it took to form the various layers between them.Radiometric dating and many other techniques are used to support the idea that this transformation process took tens and hundreds of millions of years.At least a partial explanation might be found in the fairly recently discovered fact that at least some nested hierarchical patterns to the distribution of different populations (both living and within the fossil record) seem to be strongly related to ecological and population-size factors."The common pattern of species identities associated with species area relationships is the 'nested subsets' pattern.
