Speciation is something that occurs over millions of years Species do not arise overnight. Evolutionary processes involve millions of years of genetic selection. A species maintains its uniqueness through its sexual and genetic isolating mechanisms. A species becomes more and more specialised through its struggle to optimise its reproductive chances. The position of the world's biodiversity was a major agenda point at United Nations conference that recently took place in Rio de Janeiro.
Biodiversity is the term used to describe the great variety of life forms found upon earth.
Because of factors introduced by the presence of man, such as climatic changes and the destruction of the world's rain forests, a mass extinction is now occurring which poses a grave threat to the continuance of much of the life on earth. As a loss of an important economic resource. This appears to be the primary political motivation for protecting biodiversity and the main point of disagreement between us, the First World and them, the Third World in the signing of a treaty. As a loss of pure scientific information, representing massive amounts of unique genetic data. Involved here is the notion that although some of this information might not be of practical use and economic importance now, it might very well be in the near future.
