    Reconsidering Precolumbian Human Colonization In The Galapagos Islands, Republic Of Ecuador2016Inngår i: Latin American antiquity, ISSN 1045-6635, E-ISSN 2325-5080, Vol. 27, nr 2, s. 169-183Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Fifty years ago, Heyerdahl and Skjolsvold (1956, 1990) collected material from five archaeological sites in the Galapagos Islands. They retained earthenwares of possible precolumbian origin and discarded ceramic, metal, and glass artifacts postdating the arrival of the Spanish in A.D. 1535. Consequently, they argued that each site was formed as the results of a series of discard events from unrelated short-term occupations extending from the precolumbian to the historical era, and that the earthenwares represented occasional visits by fishermen from precolumbian Peru and Ecuador. In 2005, we re -excavated the sites and collected all the excavated materials. Our results show that each class of material, irrespective of age or origin, was distributed spatially and stratigraphically in the same pattern, contradicting the former assumption of multiple, unrelated occupations. We reject the palimpsest model in favor of the null hypothesis of single-phase site occupation. Analysis of putatively precolumbian pottery using optically-stimulated luminescence dating indicates that it is mostly of historical age. Radiocarbon dating confirms that the archaeological sites are younger than the sixteenth century. Research on sedimentary cores shows probable anthropogenic impacts as restricted to the last 500 years. We conclude that there was no human occupation in the Galapagos Islands until the historical era.

    The Domestication and Early Spread Of Manioc (Manihot Esculenta Crantz): A Brief Synthesis2011Inngår i: Latin American antiquity, ISSN 1045-6635, E-ISSN 2325-5080, Vol. 22, nr 4, s. 452-468Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Owing to poor preservation of organic remains in humid environments, direct evidence of early manioc (Manihot esculenta Crantz) cultivation is exceptionally rare in datable archaeological contexts. Recent research summarized here offers new insights into the spatio-temporal framework of the initial domestication and early spread of manioc in the Neotropics. Integrating evidence from comparative plant genetics and paleoethnobotanic starch analysis to contribute to the archaeology of manioc origins, this review finds that (1) the strongest candidate for the botanical origin of domesticated manioc the wild progenitor of the root crop is the species Manihot esculenta subspecies flabellifolia (Pohl) Ciferri; (2) the geographical origin of manioc the bionic in which the progenitor evolved is most likely in the savannas, the Brazilian Cerrado, to the south of the Amazon rainforest; (3) the Cerrado is also, in our best estimate, the region of agricultural origin of initial cultivation: (4) domesticated manioc had spread from the agricultural origin by the early Holocene, possibly as early as 10,000 years ago, but certainly by 7000 B.C.; and (5) domesticated manioc was a readily available plant in most habitats of the Neotropics by the mid-Holocene, at least some 6500 years ago.
