物种概念及其界定
The median means of species concepts and species delimitation
摘要
Abstract
From the half century to now,the issue of species delimitation has long been confused by species conceptu alization, according to controversy species concepts,the boundaries and numbers of species could be great difference. Alternative species concepts agree in treating existence as a separately evolving metapopulation lineage as the primary defining property of the species category, but adopting different properties acquired by lineages during the course of divergence(e. G. Intrinsic reproductive isolation,diagnosability,monophyly)as secondary species criteria causes differ ent sounds. The paper gave a unified species concept treating a separately evolving metapopulation lineage as the only necessary property of species,and secondary species criteria as different lines of evidence relevant to assessing lineage separation. This unified concept of species had several consequences for species delimitation as follows: first,the is sues of species conceptualization and species delimitation were clearly separated; the secondary species criteria were no longer considered relevant to species conceptualization but only to species delimitation. Second,all of the properties formerly treated as secondary species criteria were relevant to species delimitation to the extent that they provide evi dence of lineage separation. Third,if possible,the presence of any one of the properties was evidence for the existence of a species,though more properties and thus more lines of evidence are associated with a higher degree of corrobora tion;Lastly,the unified species made ones liberate minds from the traditional species criteria,not tied to those properties,and develop new methods of species delimitation.关键词
