Abstract

Background: The Drimolen Palaeocave site is situated within the UNESCO Fossil Hominid Sites of South Africa World Heritage Area and has yielded numerous hominin fossils since its discovery in 1992. Most of these fossils are represented by isolated dental elements, which have been attributed to either of two distinct hominin genera, Paranthropus and Homo.

Aim: This paper provides morphological descriptions for a further 19 specimens that have been recovered from the ∼2.04-1.95 Ma Drimolen Main Quarry (DMQ) deposits since 2008. This paper also discusses the two primary hypotheses used to explain Paranthropus robustus variation: sexual dimorphism, and micro-evolution within a lineage.

Subjects and methods: These 19 fossils are represented by 47 dental elements and expand the sample of DMQ early Homo from 13 to 15, and the sample of Paranthropus robustus from 69 to 84.

Results: The evidence presented in this paper was found to be inconsistent with the sexual dimorphism hypothesis.

Conclusion: Some support was found for the micro-evolution hypothesis.

约2.04-1.95年的新人类牙齿遗骸马德里莫伦主采石场，南非。

背景：Drimolen古洞穴遗址位于联合国教科文组织南非世界遗产区人类化石遗址内，自1992年发现以来，已发现了大量人类化石。这些化石中的大多数都是由孤立的牙齿元素代表的，这些牙齿元素被认为是两个不同的人属之一，副人属和人属马Drimolen主采石场（DMQ）矿床，自2008年以来。本文还讨论了用于解释粗壮副nthropus变异的两个主要假设：两性异形和谱系内的微进化。研究对象和方法：这19个化石由47个牙齿元素代表，将DMQ早期人的样本从13个扩展到15个，将粗壮副人的样本扩展到69个到84个。结果：本文提出的证据与两性异形假说不一致。结论：微进化假说得到了一定的支持。
