几个世纪以来，美洲的人类住区一直是一个激烈辩论的话题，对于早期人类在整个大陆扩散的速度和模式，仍然没有达成共识。在试图解释北美、中美洲和南美洲早期群体的生物多样性时，研究人员为一系列分散模型进行了辩护，这些模型往往会过度简化整个大陆观察到的多样性。在这项研究中，我们旨在通过探索从墨西哥昆塔纳鲁奥洞穴中发现的四个晚更新世/早全新世标本的颅骨形态亲缘关系来为这场辩论做出贡献。这四个标本是非洲大陆已知的最早的人类遗骸之一，可以对美洲人类存在的最初数千年期间存在的生物多样性进行背景分析。通过对3D解剖标志的几何形态计量分析，将标本与世界范围内的参考系列进行比较。形态数据通过探索性视觉多变量分析和基于马氏距离的多变量分类进行分析。结果显示，每个Quintana Roo标本的形态联系模式都非常不同，这表明该地区的早期种群已经具有高度的形态多样性。这与之前对南美遗骸的研究形成了对比，并开启了北美最初种群已经具有高度形态多样性的可能性，但随着种群扩散到南部大陆，形态多样性有所减少。因此，对这些稀有遗骸的研究表明，我们可能仍然低估了早期美国人的生物多样性。
The human settlement of the Americas has been a topic of intense debate for centuries, and there is still no consensus on the tempo and mode of early human dispersion across the continent. When trying to explain the biological diversity of early groups across North, Central and South America, studies have defended a wide range of dispersion models that tend to oversimplify the diversity observed across the continent. In this study, we aim to contribute to this debate by exploring the cranial morphological affinities of four late Pleistocene/early Holocene specimens recovered from the caves of Quintana Roo, Mexico. The four specimens are among the earliest human remains known in the continent and permit the contextualization of biological diversity present during the initial millennia of human presence in the Americas. The specimens were compared to worldwide reference series through geometric morphometric analyses of 3D anatomical landmarks. Morphological data were analyzed through exploratory visual multivariate analyses and multivariate classification based on Mahalanobis distances. The results show very different patterns of morphological association for each Quintana Roo specimen, suggesting that the early populations of the region already shared a high degree of morphological diversity. This contrasts with previous studies of South American remains and opens the possibility that the initial populations of North America already had a high level of morphological diversity, which was reduced as populations dispersed into the southern continent. As such, the study of these rare remains illustrates that we are probably still underestimating the biological diversity of early Americans.
