摘要

在古人类学文献中,“马赛克”一词(马赛克进化、马赛克特征、马赛克物种等)的使用越来越频繁。为了促进文献中这一概念的使用澄清,我们在这里提出了人类进化中马赛克概念的三种不同含义的分类:1)在分支系统发育的某一阶段形态(种间和种内)不稳定性;2)在分支系统发育中,同一适应性状的多个轨迹和版本;3)特征本身是具有不同系统发育故事的子特征的复杂镶嵌(就像语言的情况一样)。我们认为,这种镶嵌模式的相关性需要一个宏观进化的解释,考虑到一般选择压力(促进相同适应的不同版本)和枝发生方法之间的相互作用,其中物种形成在人类进化中由于生态不稳定、栖息地破碎化和地理分散而起着至关重要的作用。

Mosaic evolution in hominin phylogeny: meanings, implications, and explanations.

In paleoanthropological literature, the use of the term "mosaic" (mosaic evolution, mosaic trait, mosaic species, and so on) is becoming more and more frequent. In order to promote a clarification of the use of the concept in literature, we propose here a classification in three different meanings of the notion of mosaic in human evolution: 1) morphological (inter-specific and intra-specific) instability in a certain phase of a branched phylogeny; 2) multiple trajectories and versions of the same adaptive trait in a branched phylogeny; 3) the trait itself as a complex mosaic of sub-traits with different phylogenetic stories (as is the case in language). We argue that the relevance of such mosaic patterns needs a macro-evolutionary interpretation, which takes into consideration the interaction between general selective pressures (promoting different versions of the same adaptation) and a cladogenetic approach in which speciation played a crucial role, due to ecological instability, habitat fragmentation, and geographical dispersals in human evolution.

期刊介绍: The Journal of Anthropological Sciences (JASs) publishes reviews, original papers and notes concerning human paleontology, prehistory, biology and genetics of extinct and extant populations. Particular attention is paid to the significance of Anthropology as an interdisciplinary field of research. Only papers in English can be considered for publication. All contributions are revised by the editorial board together with the panel of referees.
