Abstract
ABSTRACT Recent analyses of lake sediments in Alaska have provided physical evidence supporting the genetically inferred Beringian Standstill Hypothesis and insight into the location of its occurrence. However, the biomarkers analyzed in these sediments are relatively novel paleoenvironmental proxies, so their reliability is understandably scrutinized. Further, the timing of human presence inferred from these sediments predates the oldest, unequivocal archaeological artifacts in Alaska. In this Perspective essay, I discuss the interpretation, limitations, and implications of the sedimentary analyses. Additionally, I explore the archaeological dilemma that they pose.

期刊介绍：
PaleoAmerica disseminates new research results and ideas about early human dispersal and migrations, with a particular focus on the Americas. It fosters an interdisciplinary dialog between archaeologists, geneticists and other scientists investigating the dispersal of modern humans during the late Pleistocene. The journal has three goals: First and foremost, the journal is a vehicle for the presentation of new research results. Second, it includes editorials on special topics written by leaders in the field. Third, the journal solicits essays covering current debates in the field, the state of research in relevant disciplines, and summaries of new research findings in a particular region, for example Beringia, the Eastern Seaboard or the Southern Cone of South America. Although the journal’s focus is the peopling of the Americas, editorials and research essays also highlight the investigation of early human colonization of empty lands in other areas of the world. As techniques are developing so rapidly, work in other regions can be very relevant to the Americas, so the journal will publish research relating to other regions which has relevance to research on the Americas.
