Abstract: A serious terminological and conceptual problem of evolutionary theory is pointed out. At the present, the sexual selection could be considered a special type of natural selection as well as an independent process operating in parallel with natural selection. Some people use the term "natural" in the sense "nonartificial", "native" while others in the sense "caused by nature,, by the biotic or abiotic factors of environment". He origin of this discrepancy is clear. When Charles Darwin introduced the term "sexual selection" as the name for the process accompanying the competition among members of the same sex for mating opportunities, he failed to introduce a complementary term for all other forms of nonartificial selection. According to my opinion the term natural selection should stay reserved for its original purpose, as the general term covering all forms of nonartificial selection. there are no problems with its special form, purpose, as the general term covering all forms of nonartificial selection. There are no problems with its special form, purpose, as the general term covering all forms of nonartificial selection. There are no problems with its special form, sexual selection. For all other types of natural selection a new term - environmental selection should be introduced. |
