Coral reef#Darwin.27s paradox

The term darwin cal paradox (English: Darwin's paradox ) is used in various contexts to describe real or perceived contradictions in the reasoned by Charles Darwin 's theory of evolution.

Evolution

Darwin himself was already amazed at the observed by him during the voyage on the Beagle extreme species richness (biodiversity) of tropical seas, its nutrient content is relatively low. In coral reefs over 100 000 different species can be found; the concentration of plankton and dissolved nutrients, however, is very low. This contradiction is referenced in science darwin cal paradox. Marine biologists are pursuing various theories to resolve it.

However, diseases are studied by researchers to find potential benefits that neutralize the disadvantages. As an example, schizophrenia is noted. It appears (as many diseases) only detrimental, but according to studies, researchers found that people who suffer from schizophrenia, creative and successful in finding a partner are. Thus, there is no disadvantage, but something " non- harmful ", which this disease can exist in evolution.

Creationism

In the current political debate creationists use the term darwin cal paradox polemically to describe various phenomena which constitute contradictions to the theory of evolution in their eyes. According to the creationists claims Darwin's theory that the evolution properties of the species only survive if they provide a measurable advantage. Neutral or negative characteristics should be displaced. The existence of apparently unfavorable to the multiplication of the individual genetic traits, such as the plant to diseases, or of homosexuality, therefore refute the theory of evolution. There are also numerous examples of properties that remained bring the individual and the species is neither advantages nor disadvantages and still get about the cecum or the earlobe.

Biologists argue that the molecular representation of the phenotype is extremely complex. Genes for negative traits can be linked to genes ( eg have female relatives of homosexual men above average number of offspring, and the carriers of the hereditary blood disease sickle cell anemia are protected from malaria) increase the resistance or fertility. Many properties come about through the interaction of many individual genes.
