13. Caçadores Coletores na Amazônia: eles existem / Amazonian hunter-gatheres: they exist
The present study is a systematization of archaeological and ethnographic data on Amazonian hunter-gatherers societies, as well as a survey of paleoenvironmental studies from the same region with the aim to test and refine models that explain the colonization of Amazon forest by societies based on foraging economy. This work also contributes to new archaeolo

14. Use of Pristis spp. (Elasmobranchii: Pristidae) by Hunter-Gatherers on the Coast of São Paulo, Brazil
A utilização de pontas (dentes rostrais e ferrões) provenientes das raias é muito comum em sambaquis do litoral de São Paulo. A presença do gênero Pristis entre as espécies de elasmobrânquios estudadas reforça a hipótese da ocorrência destes animais no sudeste brasileiro e sua utilização pelos grupos de caçadores-coletores. Eu analisei 12 dent

15. A case of megacolon in Rio Grande Valley as a possible case of Chagas disease
We have been searching for evidence of Chagas disease in mummified human remains. Specifically, we have looked for evidence of alteration of intestinal or fecal morphology consistent with megacolon, a condition associated with Chagas disease. One prehistoric individual recovered from the Chihuahuan Desert near the Rio Grande exhibits such pathology. We prese

16. "Settlement systems and technological style: an interpretive porposal to Sinos River Valley precolonial settlement, Rio Grande do Sul (Brazil)" / "Sistemas de assentamento e estilo tecnológico: uma proposta interpretativa para a ocupação pré-colonial do Alto Vale do Rio dos Sinos, Rio Grande do Sul"
Technological style can be defined as the result of cultural choices reflected in different strategies of raw materials selections and debidage techniques related to the production of lithic artifacts. Therefore, it can be used to identify cultural or social identity in the archaeological record through the analysis of lithic assemblages. This concept was us

18. Why hunter-gatherer populations do not show signs of Pleistocene demographic expansions
The mitochondrial DNA diversity of 62 human population samples was examined for potential signals of population expansions. Stepwise expansion times were estimated by taking into account heterogeneity of mutation rates among sites. Assuming an mtDNA divergence rate of 33% per million years, most populations show signals of Pleistocene expansions at around 70

19. Update on HIV/SIV infections in Cameroon.
The high degree of human immunodeficiency virus type 1 (HIV-1) diversity in the Cameroonian population indicates a relatively old epidemic in this country. However, studies of pygmy 'hunter-gatherers' show only rare HIV-1 infection, mainly after contact with Bantus rather than from contact with non-human primates.

20. Y genetic data support the Neolithic demic diffusion model
There still is no general agreement on the origins of the European gene pool, even though Europe has been more thoroughly investigated than any other continent. In particular, there is continuing controversy about the relative contributions of European Palaeolithic hunter-gatherers and of migrant Near Eastern Neolithic farmers, who brought agriculture to Eur

21. Impetus for sowing and the beginning of agriculture: Ground collecting of wild cereals
The Agricultural Revolution in Western Asia, which took place some 11,000 years ago, was a turning point in human history [Childe, V. G. (1952) New Light on the Most Ancient East (Routledge & Kegan Paul, London)]. In investigating the cultural processes that could have led from gathering to intentional cultivation, various authors have discussed and tested w

22. Kusunda: An Indo-Pacific language in Nepal
The Kusunda people of central Nepal have long been regarded as a relic tribe of South Asia. They are, or were until recently, seminomadic hunter-gatherers, living in jungles and forests, with a language that shows no similarities to surrounding languages. They are often described as shorter and darker than neighboring tribes. Our research indicates that the

23. Nuts, nut cracking, and pitted stones at Gesher Benot Ya‘aqov, Israel
The Acheulian site of Gesher Benot Ya‘aqov (Israel) has revealed a unique association of edible nuts with pitted hammers and anvils. Located in the Dead Sea rift, on the boundary between the Arabian and African plates, the site dates to the Early-Middle Pleistocene, oxygen isotope stage 19. In a series of strata, seven species of nuts, most of which can be

24. Stone Age hut in Israel yields world's oldest evidence of bedding
The earliest archaeological remains of dwelling huts built by Homo sapiens were found in various European Upper Paleolithic open-air camps. Although floors of huts were found in a small number of cases, modern organization of the home space that includes defined resting areas and bedding remains was not discovered. We report here the earliest in situ bedding
