Coordinate data analysis of ancient crania from the New World reveals complexity in interpretation when addressing ancient population dispersals. The results of this study generally support a geographic patterning for the New World; however, it also revealed a much more complex and multifactorial mechanism shaping craniofacial morphology that should be considered when investigating ecogeographic models for hominin dispersals. We show that craniofacial variation is not the result of a single mechanism but is a much more complex interaction of environmental and microevolutionary forces.
分析新大陆古颅骨的坐标数据，在探讨古代人口迁徙时，会发现解释上的复杂性。本研究的结果普遍支持新大陆的地理模式；然而，它也揭示了一个更加复杂和多因素的机制，塑造了颅面形态，在研究人类扩散的生态地理模型时应该考虑到这一点。我们表明，颅面变异不是单一机制的结果，而是环境和微观进化力量的复杂相互作用。
