Katagenos Species Concept

The Katagenos Species Concept is based on the Theory of Created Kinds. It allows for a reproductive and genetic discontinuity between kinds and a continuity between breeds / species within a kind. The active dynamics for change within a Kind are communication and environmental acclimation through the mechanism of genetic selection of already existing DNA. It currently combines the terminology of Baraminology, breeding techniques, and Linnaean classification in order to express these concepts.

The Kata Genos Species Concept (KGSC) combines the terminology of Linnaean classification, Baraminology, and breeding techniques into a unified whole. It is an attempt at defining both kinds and species while allowing for a discontinuity between kinds and a continuity between animals or plants within a kind.

Defining a Species

In the KGSC, a species is defined as a breed with a specific set of defined characteristics that is able to reproduce with others of the same breed and sometimes able to hybridize with others of the same kind. This basically equates a breed with a species and allows for hybrids with other breeds/species or other genera within the kind. It generally assumes that much of current scientific classification is correct from the family level down and ignores the order level and up. However, as further research is done, the exact boundaries of kinds should be found and some changes to current classification are expected.

Genetic Compatibility

As mutations cannot be the driving force for the change found in plants and animals, another mechanism must be introduced. In the KGSC, the mechanism that is focused upon is communication for which two types are currently being considered. First is the favorable communication in selecting a mate. This is the ability of two plants or animals to recognize each other enough to induce mating behavior. The second level is the successful communication in regards to genetic reproduction. This means that the chromosomal arrangement within the individuals is similar enough to have offspring. Obviously, the closer the genetic compatibility, the more likely the offspring will be fertile and continue a breed.

Formation of Breeds

New breeds / species form when individuals within the same breed become separated or unable to communicate. The inability to communicate can have many causes such as geographical separation. When this happens the selective process of breeding out certain characteristics will move faster. This is basically equivalent to the processes of natural selection and speciation. However, it can occur rapidly as already existing traits are chosen.

Extinction

Extinction typically comes when a very selective or specialized breed can no longer maintain its specialized niche and is unable to mate with others of its breed or go back and hybridize with others of its kind. Sometimes, a breed might be able to hybridize with another of its kind, but because of changes in vocal patterns, appearance, or other method of mating recognition favorable communication has been lost and mating will not have a chance to occur.

Creation Orchard

Often, the Theory of Evolution is demonstrated with a ‘Tree of Life’. This image depicts a single tree trunk (representing an unknown common ancestor) that branches out into all the known animals. In contrast, Created Kinds is demonstrated with a forest or orchard where there are many tree trunks representing the different ancestral kinds and the limits of change. The branches and twigs on each tree represent the known breeds / species within each kind.

Fixity of Species

One phrase used in the past to describe this limited amount of change is ‘fixity of species’. When this phrase was first used, species was equivalent with a kind. It is only in modern biology that species changed meaning to represent a breeding pairs. This has caused some confusion because a fixity of species was true by the old definition, but is untrue by the modern definition. However, in modern wording, a fixity of kinds is still a basic and true concept.

Species as Breeds

The Katagenos Species Concept treats species like breeds. It defines a species as a breed within a kind with a specific set of reproductively connected characteristics that produce a recognizable form which is able to reproduce with others of the same species and potentially able to hybridize with other breeds (Species and Genera / Benim and Avot) within a Kind. It focuses on the ability to breed (including clades up to the level of Kind), gives strong attention to form / morphology, and uses habitats and geography only as indicators of where species boundaries may occur. The KSC generally assumes that current taxonomy is correct from the Family level down and ignores the Order levels and up. However, the exact boundaries vary for each kind.

How Many Species?

Defining a species by a recognizable set of characteristics could lead to a large change in the number of species depending on how fine a characteristic people use in categorizing. There have always been ‘lumpers’ and ‘splitters’ – those who would make only a few species and those who would make many species. A simple example of this is the dog species. Dogs are one species but there are hundreds of known breeds which themselves have recognizable traits. Should this become hundreds of species or remain as breeds, varieties, and forms? Major divisions are easy to make, but are smaller divisions necessary? The current system of binomial nomenclature is well established and probably does not need a significant change in the number of species. Future research will dictate where changes are needed.
