The concept of "areas of endemism", and the assumption that these patterns are always a consequence of vicariant events, are reviewed. This assumption is related to the idea that areas of endemism have well-defined limits and never share any surface with other areas of endemism because they must represent sister areas supported by sister taxa. Based on this idea, overlapping areas have been considered rarely, or ignored completely. Using a data set of mammals of North America, we test here whether the overlapping areas are indeed sister areas supported by sister taxa, thus evaluating whether vicariant events are commonly the factor producing areas of endemism.
本文回顾了“特有区域”的概念，以及认为这些模式总是由替代事件导致的假设。这一假设与以下观点相关：特有区域有明确的界限，且从不与其他特有区域有任何地域重叠，因为它们必定代表由姊妹类群支持的姊妹区域。基于这一观点，重叠区域很少被考虑，或被完全忽略。我们利用一套北美哺乳动物数据集，在此检验重叠区域是否确实为由姊妹类群支持的姊妹区域，从而评估替代事件是否通常是产生特有区域的因素。
