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. Arqueologia da memÃria: resgate da MÃe-Ãfrica
The archaeology of memory is defined, in this study, as the uncovering of the history of the African peoples, via the Atlantic, using tools such as imagery, memory and the perception of events, transmitted and stored deep in the consciousness of Afrodescendents, and in their collective world view. Its archaeological nature is based on the perception of the e

15. Estudo da dinâmica populacional do caranguejo-uçá, Ucides cordatus cordatus (LINNAEUS, 1763) (CRUSTACEA-DECAPODA-BRACHYURA), e dos efeitos de uma mortalidade em massa desta espécie em manguezais do Sul da Bahia / Study of the population dynamic of the mangrove crab, Ucides cordatus (LINNAEUS, 1753) (CRUSTACEA-DECAPODA-BRACHYURA_, and the effects of a mass mortality of this specie in Southern Bahia mangroves
The mangrove crab (Ucides cordatus cordatus) is an important fishing resource for the low income communities in Brazil and also plays a role for the environment in the mangrove ecosystem. Massive mortality events of this specie have been registered in many mangrove areas in the Northeast Region of Brazil. The first step of this work was realized from October

16. Arqueologia das práticas mortuárias em sítios pré-históricos do litoral do Estado de São Paulo. / Archaeology of mortuary practices in prehistoric sites of the São Paulo coast-line
O objetivo deste trabalho é analisar comparativamente as parcelas operacionais das práticas mortuárias entre sociedades pescadoras-coletoras que viveram no litoral centronorte de São Paulo entre em 5040 a 1381BP. Foram estudados os dados mortuários dos sítios Piaçaguera, Tenório, Mar Virado e Buracão. Entre a Baixada Santista e o litoral norte, um s

17. Recent Origin and Cultural Reversion of a Hunter–Gatherer Group
Contemporary hunter–gatherer groups are often thought to serve as models of an ancient lifestyle that was typical of human populations prior to the development of agriculture. Patterns of genetic variation in hunter–gatherer groups such as the !Kung and African Pygmies are consistent with this view, as they exhibit low genetic diversity coupled with high

18. The adaptive nature of the human neurocognitive architecture: An alternative model
The model of the human neurocognitive architecture proposed by evolutionary psychologists is based on the presumption that the demands of hunter-gatherer life generated a vast array of cognitive adaptations. Here we present an alternative model. We argue that the problems inherent in the biological markets of ancestral hominids and their mammalian predecesso

19. Geography, biogeography, and why some countries are rich and others are poor
The most important event in human economic history before the industrial revolution was the Neolithic transition from a nomadic hunter-gatherer lifestyle to sedentary agriculture, beginning ≈10,000 years ago. The transition made possible the human population explosion, the rise of non-food-producing specialists, and the acceleration of technological progre

20. Mitochondrial DNA sequences in single hairs from a southern African population.
Hypervariable parts of mitochondrial DNA (mtDNA) were amplified enzymatically and sequenced directly by using genomic DNA from single plucked human hairs. This method has been applied to study mtDNA sequence variation among 15 members of the !Kung population. A genealogical tree relating these aboriginal, Khoisan-speaking southern Africans to 68 other humans

21. 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

22. High-resolution mtDNA evidence for the late-glacial resettlement of Europe from an Iberian refugium
The advent of complete mitochondrial DNA (mtDNA) sequence data has ushered in a new phase of human evolutionary studies. Even quite limited volumes of complete mtDNA sequence data can now be used to identify the critical polymorphisms that define sub-clades within an mtDNA haplogroup, providing a springboard for large-scale high-resolution screening of human
