1. Biogeographic regionalization offers context to the geographical evolution of clades. The positions of bioregions inform both the spatial location of clusters in species distribution and where their most important boundaries are. Nevertheless, defining bioregions based on species distribution alone only incidentally recovers regions that are important during the evolution of the focal group. The extent to which bioregions correspond to centres of independent diversification depends on how clusters of species composition naturally reflect the radiation of single clades, which is not the case when mixed colonization occurred.
2. Here, we show that using phylogenetic turnover based on fuzzy sets, instead of species composition, led to adequate detection of evolutionarily important bioregions, that is, regions that account for the independent diversification of lineages. Mapping those evoregions in the phylogenetic tree quickly reveals the timing and location of major shifts of biogeographic regions. Moreover, evolutionary transition zones are easily mapped, and permit the recognition of regions with high phylogenetic overlap.
3. Our results using the global radiation of rats and mice (Muroidea) recovered four evoregions—three major evolutionary arenas corresponding to the Neotropics, a Nearctic‐Siberian, and a Paleotropical‐Australian evoregion and a fourth and fuzzy Afro‐Palearctic evoregion. Transition zones among evoregions were minimized when compared to other methods considering or not phylogenetic information, that is, the affiliation of cells to their assigned region was higher using evoregions than other approaches. Such higher affiliation values result from the lower phylogenetic overlap within evoregions, as expected when single radiations are accounted for as best as possible.
4. Evoregions is a useful framework whenever the question is related to the identification of the most important centres of a group's diversification history and its evolutionary transitions zones.

Evoregions：跨生物地理区域的系统发生更新的映射移动

1. 生物地理区域化为进化枝的地理进化提供了背景。生物区域的位置既可以指示簇在物种分布中的空间位置，又可以指示它们最重要的边界在哪里。但是，仅根据物种分布来定义生物区域只能偶然地恢复在焦点小组演变过程中重要的区域。生物区域对应于独立多样化中心的程度取决于物种组成簇如何自然反映单个进化枝的辐射，而发生混合定居则不是这种情况。
2. 在这里，我们表明，使用基于模糊集而不是物种组成的系统发生更新，可以充分检测出具有重要进化意义的生物区域，也就是负责谱系独立多样化的区域。在系统发育树中绘制这些evoregions很快就会揭示出生物地理区域主要变化的时间和位置。此外，进化过渡区很容易标绘，并允许识别具有高度系统发育重叠的区域。
3. 我们利用大鼠和小鼠的全球辐射（Muroidea）的结果，恢复了四个evoregions-对应于新热带的三个主要演化区域，一个近西伯利亚-西伯利亚，一个古热带-澳大利亚evoregion和一个第四且模糊的非洲-古生物evoregion。与考虑或不考虑系统发育信息的其他方法相比，evoregions之间的过渡区域最小化，也就是说，使用evoregions的细胞与其指定区域的联系要高于其他方法。这种较高的隶属度值是由evo区内较低的系统发育重叠导致的，这是在尽可能考虑单个辐射时所期望的。
4. 每当问题与确定集团多元化历史的最重要中心及其演变过渡区有关时，Evoregions都是有用的框架。
