In line with some of our recent coverage involving the cultural advances in the territories, Phys.org publishes this piece, highlighting evidence of the complexity of humans in Puerto Rico.
The earliest inhabitants of Puerto Rico might have used common burial sites and mortuary practices across many centuries, according to a study published April 26, 2023, in the open-access journal PLOS ONE by William J. Pestle of the University of Miami, Florida and colleagues.
Puerto Rico was inhabited by people for several thousand years prior to the Ceramic Age, but little is known about these earliest inhabitants due to a paucity of evidence and research, with only 20 ancient individuals reported from this time period. In this study, Pestle and colleagues describe five adult individuals from burials at the Ortiz site in Cabo Rojo, southwestern Puerto Rico, representing a substantial addition to archaeological information about this time period.
Radiocarbon dating of the remains yielded ages as old as 1800 BC and as young as 800 BC, thus including the oldest directly dated human remains from Puerto Rico and representing as much as 1,000 years of burials at the Ortiz site. The mortuary practices, including the positioning of the bodies and the associated grave goods, are similar to other early sites, indicating standard burial practices over many centuries. In addition, Strontium isotope analysis also indicates that these buried individuals were born in different nearby geographical locales. Thus, the Ortiz site might have held cultural significance as a common mortuary space for various local communities.
