%X In the last ten years, new fossil, archaeological, and genetic data have significantly altered our understanding of the peopling of the Old World in the Late Pleistocene. Scholars have long been challenged to define humanity¡¯s place in evolution and to trace our phylogeny. Differences in the skeletal morphology of hominin fossils have often led to the naming of distinct new species, but recent genetic findings have challenged the traditional perspective by demonstrating that modern human DNA contains genes inherited from Neanderthals and Denisovans, thus questioning their status as separate species. The recent discovery of Homo floresiensis from Flores Island has also raised interesting queries about how much genetic and morphological diversity was present during the Late Pleistocene. This paper discusses the nature and implications of the evidence with respect to Homo floresiensis, Neanderthals, and Denisovans and briefly reviews major Late Pleistocene discoveries from the last ten years of research in the Old World and their significance to the study of human evolution. 1. Introduction In the literature of human evolution, recent years have been marked by new questions of what it means to be human. Scholars have long been challenged to define humans¡¯ place in evolution and to trace our phylogeny. Differences in the skeletal morphology of hominin fossils have often led to the naming of distinct new species. Species are traditionally and most often defined as a population or group of populations capable of interbreeding and producing fertile offspring [1], although Mayden [2] more recently have identified at least 24 alternative species conceptualizations (see also de Queiroz [3] for a discussion of modern versus traditional species definitions). Recent genetic findings have challenged the traditional biological perspective by demonstrating that modern human DNA contains genes inherited from Neanderthals and Denisovans [4¨C6]. Not only do modern humans partially share their lineage but genetic evidences also indicate that these different hominins were capable of interbreeding and producing viable offspring, thus questioning their status as separate species. Genetic data to date indicate that at least Neanderthals, anatomically modern humans (AMH, i.e., humans with skeletons similar to those of present-day humans), and Denisovans were variants of a single breeding population of Homo, even though they present vast spatiotemporal differences in their skeletal morphology and artifactual productions. Despite these findings, however, in general the human
