Scientists find 800 year-old cojoba remains on Taino artifacts

Archaeological starch grains consistent with those produced and stored in modern cojoba (Anadenanthera peregrina) seeds were identified, for the first time in the West Indies, in a coral milling base recovered in a small precolonial habitation site of Eastern Puerto Rico, in a context dated to A.D. 115–1250. Ethnohistoric, ethnographic, and previous archaeological data on cojoba from the West Indies and South America were surveyed in order to form plausible sociocultural interpretations of the findings.

Protecting the scaly-naped pigeon

The scaly-naped pigeon (Patagioenas squamosa) is threatened by hunting in the Caribbean. At present, the pigeon is abundant in Puerto Rico, but overharvesting is a major concern; therefore, the development of a sustainable harvest strategy is a management priority. The management objective of the harvest strategy is to maximize hunting opportunity while keeping the population above an abundance threshold (NT) of 260,000 pigeons.

La evidencia del pasado puede ser guardada en formato digital o en formato análogo; mediante fotografía o árboles genealógicos. Sin embargo, estas herramientas suelen ser poco útiles si queremos explorar nuestra historia hace siglos o milenios atrás.

Un concepto que se observa en diferentes campos del conocimiento es el de paradigma. Un paradigma establece lo que se asume como correcto o básico en una disciplina. Son estos axiomas los que nos ayudan a interpretar las cosas desde un punto de vista u otro. Existen paradigmas en áreas tan diversas como la economía, las artes, la sociología y las ciencias.
