Strontium isotope ratios (87Sr/86Sr) are gaining considerable interest as a geolocation tool and now widely applied in archaeology, ecology, forensic research. However, their application for provenance requires the development of baseline models predicting surficial 87Sr/86Sr variations (“isoscapes”). A variety empirically-based process-based have been proposed to build terrestrial isoscapes but, current forms, those not mature enough be integrated with continuous-probability surface used...

A method for mapping strontium isotope ratio ( 87 Sr/ 86 Sr) variations in bedrock and water has been recently developed use the interpretation of Sr datasets provenance studies. The process adopted simplifying assumption that (Sr) comes exclusively from weathering underlying bedrock. scope this bedrock‐only is thus limited to systems where contributions other sources are minimal. In paper, we build on by developing a mixing model fluxes multiple bioavailable pool. new source includes: (1)...

Substantial progress in the application of multiple isotope analyses has greatly improved ability to identify nonlocal individuals amongst archaeological populations over past decades. More recently development large scale models spatial isotopic variation (isoscapes) contributed geographic assignments human and animal origins. Persistent challenges remain, however, accurate identification individual origins from skeletal data studies (and animal) migration provenance. In an attempt develop...

Significance Ancient DNA has revolutionized the field of archaeology, but in Caribbean and other tropical regions world, work been hampered by poor preservation. We present an ancient human genome from use it to shed light on early peopling islands. demonstrate that ancestors so-called “Taino” who inhabited large parts pre-Columbian times originated northern South America, we find evidence they had a comparatively effective population size. also show native components some modern genomes are...

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...

Abstract Analysis of the spatial and temporal structure global island colonization allows us to frame extent insular human cultural diversity, model impact common environmental factors cross-culturally, understand contribution maritime societies big historical processes. No such analysis has, however, been undertaken since 1980s. In this paper we review update patterns in colonization, synthesizing data from all major groups theaters undertaking quantitative qualitative these data. We...

This study explores the potential of carbon and oxygen isotope data from human enamel carbonate (n = 50) to contribute mobility studies in Caribbean. Most results display limited variation, with substantial overlap between islands. However, a few individuals El Chorro de Maíta, Cuba possess relatively low δ18O high δ13C. Two these were previously identified as possible non-Antillean immigrants on basis strontium isotopes, bioarchaeological mortuary evidence. The provide additional evidence...

Human populations have been shaped by catastrophes that may left long-lasting signatures in their genomes. One notable example is the second plague pandemic entered Europe ca. 1,347 CE and repeatedly returned for over 300 years, with typical village town mortality estimated at 10%–40%.1Slack P. The Impact of Plague Tudor Stuart England. Routledge & K. Paul, 1985Google Scholar It assumed this high affected gene pools these populations. First, local population crashes reduced genetic...

The complex relationships between humans and dogs (Canis lupus familiaris) have a very deep unique history. Dogs accompanied as they colonised much of the world, were introduced via human agency into insular Caribbean where became widespread throughout Ceramic Age. It is likely that dynamic interactions humans, dogs, their environments in spatially, chronologically, socially variable. However, almost no research has specifically addressed nature, or potential variability, human/dog this...
