Abstract
Sisters of a sistergroup are taxa that share a more recent common ancestry with each other than either does with any other taxon One of the most interesting aspects of evolution concerns the very different histories in terms of morphological diversification that such sistertaxa often have Elsewhere I have suggested that the causes of different kinds of evolution may be especially well studied in lowranking sistergroups that include a fossil record plus extant survivors and that are still in a phase of evolutionary radiation Vrba 1980a The bovid tribes Alcelaphini blesbuck—hartebeest—wilde—beest group and Aepycerotini impalas provide such a case
