The idea that both patterns of shrub growth after fire are advantageous under certain circumstances supports creation scientists' belief that there is a plan in nature. Some people have appealed to chromosomal reorganization as a way of getting large changes in a hurry, as is needed according to the notion of punctuated equilibrium. It is shown here that there is no evidence that such changes will really lead to anything which is new, viable, and improved. Punctuated equilibrium is still a hypothetical process, for which no mechanism can be found. A Working Hypothesis A. J. Jones, Ph.D. Modern evolutionary theory is based on the assumption that all of heredity has its basis in the DNA genes.
Evidence is presented here to show that that assumption is false.
There are, in fact, two major interacting systems of heredity. The implications of these facts for Creationist research are discussed. The sickle cell story is often put forward as a demonstration of evolution. Here recent medical knowledge concerning the trait is reviewed. It is seen that in sickle cell nothing has evolved, improved, or increased in complexity.
