For biologists, kinds of organisms are the fundamental building blocks, just as the chemical elements are for a study of chemistry. Rolf Siewing defines “kind” according to two criteria [S6, p. 172]:
- From the view of reproductive biology, a kind is a fertile community which exists under natural conditions and amongst whom unrestricted gene interchange is possible (biospecies).
- From the structural viewpoint a kind possesses the same constructional plan (morphospecies).
Evolution: In the evolutionary view, all systematic categories are assumed to be related, and, consequently, that a phylogenetic tree exists. In setting up this tree, evolution is faced with an irresolvable problem. Peters and his co-authors (quoted in [G2, p. 49]) concede that one cannot set up any reconstruction that is inherently plausible. Some yardstick for measuring its plausibility must be available. In any case, we have a preordained theory, namely the theory of evolution. The circularity of this reasoning becomes clear: What has to be proved, has already been assumed to start with. The problem of evolutionary systematics to trace unknown, untraceable relationships, is painted as follows by Siewing [S6, p. 173]:
It is like an observer who views a flooded orchard with only the tips of the branches visible above the water. He does not know how these branches connect with one another, nor how they eventually connect with the tree trunks. The major part of evolution containing the gaps in the lines of descent is hidden under water. These gaps must be bridged methodically.
Scientific Objections: The essential quantity in all life-forms is the information contained in the genes. The pre-supposed evolutionary tree of descent (phylogenesis) is not controlled nor guided by information; thus, it is an impossibility according to informatics theory [G9, p. 16–17]. On the other hand, the development of embryos (ontogenesis) is a process which is controlled and guided by information. Recent discoveries in molecular biology have shown that very many mechanisms in living cells exist for the purpose of transferring exact information [S2]. This basic requirement for the constancy of the various kinds of organisms is conceded by G Osche, an evolutionary biologist [O2, p. 53]:
The set of genes of an organism is a finely tuned team, a balanced “genome” whose harmonious cooperation determines the orderly development of a living being. This finely balanced genome is extremely important for the organism, and is always transmitted unchanged at every single step of cell division and the division of cell nuclei and chromosomes. Before every cell division, the genetic code must be replicated, in such a way that exactly the same chemically defined configuration is formed. This identical replication of the genes guarantees the constancy of genetic information. Roughly speaking, this replication is responsible for the phenomenon that storks always hatch from stork eggs with all the characteristics of this kind of bird.
