Abstract

The relative importance of the two main cranial complexes, the neurocranium and the splanchnocranium, has been examined in the five species of extant hominoids and in a huge sample of extinct hominins using six standard craniometric variables that measure the length, width and height of each cranial module. Factor analysis and two-block partial least squares were used for establishing the major patterns of developmental and evolutionary integration between both cranial modules. The results obtained show that all extant hominoids (including the anatomically modern humans) share a conserved pattern of developmental integration, a result that agrees with previous studies. The pattern of evolutionary integration between both cranial modules in australopiths runs in parallel to developmental integration. In contrast, the pattern of evolutionary and developmental integration of the species of the genus Homo is the opposite, which is probably the consequence of distinctive selective regimes for both hominin groups.

摘要

利用六个测量每个颅骨模块长度、宽度和高度的标准颅骨测量变量,对现存的五种类人猿以及大量已灭绝的古人类样本,研究了两个主要颅骨复合体——脑颅和面颅的相对重要性。采用因子分析和两模块偏最小二乘法来确定两个颅骨模块之间发育和进化整合的主要模式。所得结果表明,所有现存类人猿(包括解剖学上的现代人类)都具有一种保守的发育整合模式,这一结果与先前的研究一致。南方古猿两个颅骨模块之间的进化整合模式与发育整合模式并行。相比之下,智人属物种的进化和发育整合模式则相反,这可能是这两个人类群体不同选择机制的结果。
