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.
