Earliest evidence of sedentism in the Antilles: Multiple isotope data from Canímar Abajo, Cuba
View abstract on PubMed
Summary
This summary is machine-generated.Early Antillean populations show evidence of reduced residential mobility, with isotopic analysis indicating a shift from sedentary lifeways to increased population movement and diverse traditions over time. This study offers the earliest isotopic evidence for low mobility in the Antilles.
Area Of Science
- Archaeology
- Bioarchaeology
- Isotope Geochemistry
Background
- Early Antillean populations were traditionally viewed as highly mobile hunter-fishers/gatherers.
- Recent findings suggest some groups cultivated domestic plants, but their residential mobility remains debated.
- Understanding sedentism is key to interpreting social relations, complexity, and adaptations of past communities.
Purpose Of The Study
- To investigate mobility patterns of early Antillean groups using stable isotope analysis.
- To determine if the adoption of domesticates correlated with decreased residential mobility.
- To examine changes in population movement and lifeways at the Canímar Abajo site.
Main Methods
- Analysis of enamel strontium (⁸⁷Sr/⁸⁶Sr), oxygen (δ¹⁸Oen), and carbon (δ¹³Cen) isotopes.
- Examination of 44 human teeth from the Canímar Abajo site, containing the oldest human remains in the insular Caribbean.
- Comparison of isotopic data from different funerary periods within the site.
Main Results
- Homogeneous strontium isotope values in older funerary remains (cal. BC 2237-790) suggest a sedentary population relying on local, coastal resources.
- Later reuse of the mound (cal. AD 403-1282) revealed increased population mobility, with nonlocal individuals and diverse dietary/burial practices.
- Isotopic data indicate a transition from low-level residential mobility to greater movement over time.
Conclusions
- The earliest Antillean populations at Canímar Abajo exhibited low residential mobility, challenging traditional views.
- Later periods at the site show increased mobility and the presence of nonlocal individuals.
- Isotope analysis provides crucial insights into the changing lifeways and mobility of early Caribbean populations.

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.
Phylogenetic trees illustrate the evolutionary relationships among these organisms. Scientists infer organisms’ common ancestry by evaluating shared morphological and genetic characteristics....
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.
The collection of fossils within sedimentary rocks give a record of common ancestry and often depicts the history of...
Radioactivity is a spontaneous disintegration of an unstable nuclide and is a random process, as all the nuclei in the sample do not decay simultaneously. The number of disintegrations per unit time is called the activity (A), which is directly proportional to the number of nuclei in the sample. The decay constant (λ) is an average probability of decay per nucleus in unit time.
The SI unit for activity is the becquerel, which is one disintegration per second. Another unit of activity is the...
