美洲最初的人口已经被证明是重建全球史前史中最具挑战性的事件之一，具有挑战性的是，研究人员与早期考古遗址保护的变幻莫测作斗争，并且对人类进入的日期和地点，分散的速度和方向以及在更新世末期对气候变化的各种文化反应的争论仍在继续。尽管我们对这些问题的理解最近取得了许多进展，特别是在遗传学和新的考古发现领域，但该领域仍然面临着数据的采样和质量，定义的研究问题以及应用的认识论和理论的限制。早期美国研究的理论发展是不平衡的，其对早期人类移民全球问题的贡献受到限制。本文从考古学、遗传学和生物人类学的角度讨论了美洲第一批居民的过程中已知和未知的问题。一些方法来填补空白的数据，方法和更广泛的概念化的过程也被认为是。
The initial peopling of the Americas has proved one of the most challenging episodes in reconstructing global prehistory, challenging because researchers struggle with the vagaries of early archaeological site preservation, and debates continue over the date and place of human entry, the rapidity and direction of dispersion, and the variety of cultural responses to climatic change during the terminal Pleistocene period. Despite many recent advances in our understanding of these issues, especially in the areas of genetics and new archaeological discoveries, the field continues facing limitations in the sampling and quality of data, the research problems defined, and the epistemologies and theories applied. Theoretical development of first American studies has been uneven, and its contribution to global issues of early human migration has been restricted. This essay discusses what is known and not known about the process of the first peopling of the Americas from the perspective of archaeology, genetics, and bioanthropology. Some approaches to fill voids in data, methods, and the broader conceptualization of the process also are considered.
