Abstract
Wild species are products of natural evolution in centers of diversity. They are not manipulated or used by man. Evolution is brought about by the interaction of both abiotic (physical and chemical) and biotic (living organisms, mainly pests and diseases) factors with genetically variable plant populations. This has resulted in the wealth of variation found within and among species. In the centers of diversity the species may coexist, but they remain largely separated by external and internal barriers developed in the course of evolution.
