在这篇支持和反对原始人分支内分类多样性的证据的回顾中，我们首先看看对原始人化石记录进行简单的“阶梯状”解释的逻辑和历史。然后，我们在一系列的时间间隔中查看原始人化石记录，并使用目前公布的关于每个分类群首次和最后出现日期的证据来决定是否应该将一个物种或标本包括在一个或多个间隔中。在每个时间间隔内，我们考虑不止一个原始人物种被抽样的证据的强度。关于分类多样性是否存在的决定取决于所使用的阿尔法分类假说，尽管我们使用了对原始化石记录的相对专门的解释，但我们也探索了对阿尔法分类的更具包容性的解释将对原始分类多样性的评估产生什么影响。在我们看来，除了最古老的(7-5 Ma)以外，所有其他的时间间隔都至少有一个得到很好支持的出租车多样性的例子，有几个有多个例子。总而言之，并不是所有新的原始人分类群都是平等地产生的，但尽管分类群的多样性可能并不像一些人声称的那样普遍，但它是从4 Ma到约40 ka前的原始人支系的一个特征。
In this review of the evidence for and against taxic diversity within the hominin clade, we begin by looking at the logic and the history of simple "ladder-like" interpretations of the hominin fossil record. We then look at the hominin fossil record in a series of time intervals and use current published evidence about the first and last appearance dates of each taxon to decide whether a species or specimens should be included in one, or more, of the intervals. Within each time interval, we consider the strength of the evidence that more than one hominin species is sampled. Decisions about whether taxonomic diversity exists depend on what alpha taxonomic hypotheses are used and although we use a relatively speciose interpretation of the hominin fossil record, we also explore what impact more inclusive interpretations of alpha taxonomy would have on assessments of hominin taxic diversity. With the exception of the oldest (7-5 Ma) all of the other time intervals have in our judgment at least one well-supported example of taxic diversity and several have multiple examples. In summary, not all new hominin taxa are created equally, but while taxic diversity may not be as prevalent as some have claimed, it is a feature of the hominin clade from 4 Ma until c.40 ka years ago.
