Ancient DNA traces the history of hepatitis B Hepatitis virus (HBV) infections represent a worldwide human health concern. To study this pathogen, Kocher et al . identified 137 remains with detectable levels dating between 400 and 10,000 years ago. Sequencing analyses these ancient viruses suggested common ancestor 12,000 20,000 There is no evidence indicating that HBV was present in earliest humans as they spread out Africa; however, likely populations before farming. Furthermore, Americas...
A complex dispersal into the Caribbean The settlement of and genetic relationships among pre-European people remain a mystery. After examining 93 ancient genomes dating to range from about 3200 400 years ago, Nägele et al. suggest that at least three separate colonization events, including previously unknown wave, were connected radiation events in North America. two more lineages coexisted Cuba but fully genetically, with later movement region third group South study not only informs on...
This paper explores the potential of combining different isotope systems from tissues to improve resolution when reconstructing breastfeeding and weaning practices (BWP) in archaeology. Additionally, we tested whether changes diet can be detected deciduous teeth. Rib collagen samples 22 infants/children archaeological site Bacuranao I (Mayabeque, Cuba) were processed for nitrogen (δ15N) carbon (δ13Cco) stable isotopes assessed using a Bayesian model (WARN). In addition, enamel 48 teeth 30...
In this paper, we sought to examine whether people with different lifeways, as evidenced by their mobility patterns and dietary practices, inhabited the Antilles in early precolonial time. We also aimed explore spatiotemporal trends. New previously published enamel strontium, oxygen, carbon isotope data were combined bone apatite collagen nitrogen assess diet of 146 individuals from eight sites Cuba. At least three mobility, associated signals, identified. contrast low 87Sr/86Sr δ13Cen...
The general lack of well-preserved juvenile skeletal remains from Caribbean archaeological sites has, in the past, prevented evaluations dietary changes. Canímar Abajo (Cuba), with a large number and adult remains, provided unique opportunity to fully assess paleodiets an ancient population. Ages for start end weaning possible food sources used were inferred by combining results two Bayesian probability models that help reduce some uncertainties inherent bone collagen isotope based paleodiet...
Twelve accelerator mass spectrometry (AMS) radiocarbon dates from the shell-matrix site of Canímar Abajo (Matanzas, Cuba) are reported. Eleven were obtained directly human bone collagen in burials and one was charcoal recovered a burial context. The stratigraphy presents two episodes activity separated by shell midden layer. AMS fall into compact clusters that correlate remarkably well with stratigraphy. older to between 1380–800 cal BC (2σ) younger AD 360–950 (2σ). compared eight...
Abstract Human breastfeeding is a biocultural process shaped by the interaction of numerous biological, cultural, economic, and social factors. Although previous studies have found that society's subsistence economy alone does not determine weaning timing, may still profound effect on food choices. This paper analyses nitrogen carbon stable isotopes in bone collagen apatite individuals from six precolonial Caribbean sites grouped into four categories: Hunter‐Fisher‐Gatherers (Cueva del...

The early populations that inhabited the Antilles were traditionally understood as highly mobile groups of hunters/fishers and gatherers. Although more recent data have demonstrated some engaged in production domestic plants cultivars, questions remain about other aspects their lifeways, including whether adoption domesticates was accompanied by a decrease residential mobility. level sedentism population is an instrumental variable to understand community social relations complexity,...
Paleoethnobotanical and stable isotope studies have demonstrated that the indigenous groups populated Antilles, traditionally understood as dependent exclusively on wild resources, cultivated consumed both C3 C4 plants even before arrival of ceramic-bearing Arawak groups. However, relative importance cultigens differential use plants, especially maize, between populations individuals remains unknown. In this paper we combined analysis isotopes (δ15N, δ13Cco, δ13Cen, δ13Cap, δ34S) 27 from...
ABSTRACT Fewer than 200 radiocarbon ( 14 C) dates with secure contextual information are available for Cuba, making it challenging to reconstruct Caribbean indigenous population dynamics, their identities and interactions. In this paper, we discussed 21 accelerator mass spectrometry (AMS) C from two mounds (M1 M2) at the Playa del Mango site (Granma province, Cuba), traditionally associated Banwaroid stone tool tradition. The ΔR calculated was –132.0 ± 176 –164.0 68. chronology of burials...
As one of the unique features human life history, breastfeeding is key area research on past populations. Infant feeding practices have important implications not only for health, growth, and development children, but also population dynamics, as they affect fertility, morbidity, mortality patterns. More importantly, weaning (BWP) are variable shaped by complex interactions cultural biological givens any group, from availability nutrition associated beliefs, to ways in which group constructs...
Este trabajo sistematiza la información relacionada con uno de los artefactos más singulares del registro arqueológico cubano. Singularidad marcada por su tipología, escasa presencia y carencia estudios científicos sobre uso en las poblaciones baja escala productiva. El estudio revela un universo estos objetos conservados fondos o colecciones, sus detalles tecno-tipológicos, así como contexto cultural cronológico. Se realizaron arqueométricos una muestra diecisiete procedentes asentamientos...
Abstract The development of digital technologies and the use advanced photogrammetry programs for modeling archaeological excavations sites have opened new possibilities spatial analysis in archaeology reconstruction contexts. In addition, these tools allow us to visually preserve features future facilitate dissemination heritage local communities general public.
