60,000 years of interactions between Central and Eastern Africa documented by major African mitochondrial haplogroup L2

Mitochondrial DNA (mtDNA) haplogroup L2 originated in Western Africa but is nowadays spread across the entire continent. L2 movements were previously postulated to be related to the Bantu expansion, but L2 expansions eastwards probably occurred much earlier. By reconstructing the phylogeny of L2 (44 new complete sequences) we provide insights on the complex net of within-African migrations in the last 60 thousand years (ka). Results show that lineages in Southern Africa cluster with Western/Central African lineages at a recent time scale, whereas, eastern lineages seem to be substantially more ancient. Three moments of expansion from a Central African source are associated to L2: (1) one migration at 70-50 ka into Eastern or Southern Africa, (2) postglacial movements (15-10 ka) into Eastern Africa; and (3) the southward Bantu Expansion in the last 5 ka. The complementary population and L0a phylogeography analyses indicate no strong evidence of mtDNA gene flow between eastern and southern populations during the later movement, suggesting low admixture between Eastern African populations and the Bantu migrants. This implies that, at least in the early stages, the Bantu expansion was mainly a demic diffusion with little incorporation of local populations.

A new sector of Via XVII Necropolis in Bracara Augusta: the High Empire phase

Between 2008 and 2009 a preventive excavation supervised by the Unit of Archaeology of the University of Minho was conducted in an area with approximately 5000 square meters allowing the identification of a wide sector of the Via XVII necropolis, which is one of the five roman necropolises known to have existed in Bracara Augusta. The findings enabled us to define a typological framework related with incinerations, to understand the internal organization of the necropolis and recover the ritual marks of the funerary practices between the first century BC and the second century AD.

Entrevista com Maria Manuela dos Reis Martins: reflexões sobre a Arqueologia Urbana, a paisagem e o território

Arquitetura doméstica em Bracara Augusta

As escavações realizadas em Braga ao longo das últimas três décadas forneceram dados que permitem analisar neste trabalho a temática da arquitetura doméstica de Bracara Augusta. Durante este período foi reunido um significativo acervo de dados arqueológicos que, apesar de desiguais quanto ao volume e qualidade de informação, possibilitam a caracterização de algumas habitações, ainda que exclusivamente incluídas na categoria de domus, já que o registo arqueológico ainda não forneceu, qualquer outro tipo de estrutura habitacional urbana. Pretende-se contextualizar este tipo de casa, analisando as diferentes partes orgânicas, evidenciando as suas especificidades formais, construtivas e funcionais.

Crustáceos no cerrito Ariano Souza, Rio Grande, Rio Grande do Sul e distribuição de Callinectes sapidus (Brachyura, Portunidae)

While all species of the genus Callinectes Stimpson, 1860 have a continuous distribution on the Atlantic coast of the Americas, Callinectes sapidus Rathbun, 1896 is the only one with disjunct distribution. Considering that this species was introduced in Europe and Japan, it has been suggested that the occurrence of C. sapidus on the southern coast of Brazil was due to the transport by ballast water. In the archaeological site Ariano Souza, located in the estuary of the Patos Lagoon (southern Brazil), remains of crustaceans, including claws of approximately two thousand years ago, were found. A preliminary analysis of this material showed Callinectes chelae. Because this archaeological site is located inside the estuary, it has been hypothesized that these chelae belong either to C. sapidus or to C. danae Smith, 1869. A comparison between pincers collected in the archaeological and pincers of these two species (90 dactyls, 30 of each type) was performed. The analysis (ANOVA) considered the variability of seven characters of the dactyls, and demonstrated the existence of two groups. Results showed that the measured characters suffice to separate these species, and indicated that the material found in the archaeological site belongs to C. sapidus. The hypothesis of the introduction of C. sapidus in the area is rejected. The possible biogeographic history of the species is discussed.
