“…Whether the peripheral origin of the earliest domesticated populations is due to the plants themselves or to human activity is an interesting question. During the terminal Pleistocene, when humans were already in Amazonia, much of western Amazonia is thought to have been forested, while large parts of central and eastern Amazonia were open forest that was quite different from current open forests [147][148][149]. The drier areas along the northern and southern peripheries probably expanded further into the basin than they do currently.…”

Molecular analyses are providing new elements to decipher the origin, domestication and dispersal of native Amazonian crops in an expanding archaeological context. Solid molecular data are available for manioc (Manihot esculenta), cacao (Theobroma cacao), pineapple (Ananas comosus), peach palm (Bactris gasipaes) and guaraná (Paullinia cupana), while hot peppers (Capsicum spp.), inga (Inga edulis), Brazil nut (Bertholletia excelsa) and cupuassu (Theobroma grandiflorum) are being studied. Emergent patterns include the relationships among domestication, antiquity (terminal Pleistocene to early Holocene), origin in the periphery, ample pre-Columbian dispersal and clear phylogeographic population structure for manioc, pineapple, peach palm and, perhaps, Capsicum peppers. Cacao represents the special case of an Amazonian species possibly brought into domestication in Mesoamerica, but close scrutiny of molecular data suggests that it may also have some incipiently domesticated populations in Amazonia. Another pattern includes the relationships among species with incipiently domesticated populations or very recently domesticated populations, rapid pre-or post-conquest dispersal and lack of phylogeographic population structure, e.g., Brazil nut, cupuassu and guaraná . These patterns contrast the peripheral origin of most species with domesticated OPEN ACCESSDiversity 2010, 2 73 populations with the subsequent concentration of their genetic resources in the center of the basin, along the major white water rivers where high pre-conquest population densities developed. Additional molecular genetic analyses on these and other species will allow better examination of these processes and will enable us to relate them to other historical ecological patterns in Amazonia.

“…During the Late Pleistocene, dry phases repeatedly reduced considerably the size of the tropical forest around the globe, around 60 kya, 40 kya, 25-11 kya (Dupont et al 2000, Maley 2004, Sémah & RenaultMiskovsky 2004, Sultan et al 2001, Van der Hammen & Hooghiemstra 2000. During the Last Glacial Maximum in Central Africa, for example, the rainforest at ~20 kya had almost disappeared except for a few crucial refugia that are still biodiversity hotspots, from where rainforest species expanded once climatic conditions improved and stabilized during the Holocene.…”

The sediments from the Coari lake, a "terra firme" lake sculpted into Plio-Pleistocene deposits, and the Acará lake, a flooding-type lake developed on Quaternary sediments in the floodplain of the mid-Solimões river, in the western Amazônia, Brazil, were studied to investigate the environmental condition of their developing. This study includes mineral composition, geochemistry, Pb isotope, palinology, radiocarbon-age and morphological framework of the lakes obtained from SRTM satellite images. The geological and the environmental conditions in the two lakes are highly variable and suggest that their evolution reflect autogenic processes under humid rainforest condition. Although kaolinite, quartz, muscovite, illite, and smectite are the main minerals in both lakes, the geochemistry indicates distinct source, the Acará lake sediments have higher concentrations of Al 2 O 3 , Fe 2 O 3 , FeO, CaO, K 2 O, MgO, Na 2 O, P 2 O 5 , Ba, V, Cu, Ni, Zn, Pb, Sr, Li, Y and La and have more radiogenic Pb than the Coari lake sediments. The radiocarbon ages suggest that at 10160 yr BP the Coari lake started to be developed due to avulsion of the Solimões river, and the Acará lake was formed by the meander abandonment of Solimões river retaining its grass dominated shore at ca. 3710 yr BP.
