| Sumario: | The purpose of this essay is to express my concerns with genetic models focused on the early peopling of the Americas. My attempt here is simply to raise questions and to discuss ways, from the perspective of anthropological archaeology, to enhance the contributions of genetic studies and hopefully to bring closer together genetic and archaeology studies on the early peopling issue. One concern is that the findings of genetic models must be better reconciled with previous ones and with the results of physical anthropology, archaeology, and paleoecology. Others are the comparability of genetic data derived from living groups and from ancient human remains, demographic histories and definitions of demographic units of analysis, sampling designs and representation of data, founder populations, genetic drift and selection, reliability of molecular clocks, and data collection strategies and contamination. There also must be a tacit recognition that geneticists must depend more on the archaeological record, not only for the recovery of human remains, but to a certain degree the co-interpretation of the modern DNA and aDNA data and their context and chronology, as well as the production of broader questions in anthropology. This essay does not pretend to represent the concerns of all archaeologists, but a majority of colleagues that I have interacted with over the past few decades. |
