The beginnings of human occupation of the Amazon go back to the Pleistocene-Holocene transition. Already at 8500 BP there are signs of human occupation in different settings, both riverine and hinterland, throughout the whole basin. The beginnings of ceramic production may be early as well, with dates possibly from the eighth millennium BP and certainly from the sixth millennium BP. Paradoxically, however, with the exception of localized areas, the archaeological record of the middle Holocene across the Amazon is characterized by large hiatuses with few if any signs of human occupation. Hence, although there are signs of continuous human occupation and population aggregation starting at 4500 BP at places such as the Upper Madeira, the Upano basin and the mouth of the Amazon, these seem to be isolated phenomena since no corresponding developments are seen at the same time elsewhere in the Amazon. It is rather later, from around the anno domini on, that a widespread and visible pattern of population growth, site aggregation and noticeable anthropic landscape changes become visible. These changes are matched, in the archaeological record, by the sudden appearance of large sites with deep stratified ceramic deposits associated with anthropic dark soils, raised fields and causeways, large villages surrounded by moats and connected by road networks and of artificial residential and funerary mounds associated with elaborated pottery, quasi-urban settlement systems, polished stone statuettes, long-range trade networks, and the construction of circular megalithic structures. Do theses hiatuses mean that the Amazon basin was scarcely occupied during the mid-Holocene? Is there a taphonomic bias towards the destruction or poor visibility of sites dating from this interval? Can these apparent hiatuses be correlated with events of climatic change? Current data from pollen records, carbon isotopes in stable organic matter, and fluvial geomorphology show that the mid-Holocene in the Amazon could have been drier than the present. If this is true, it is likely that many of the archaeological sites from this time are either destroyed, under water or under tons of alluvial sediment. Conversely, it is also possible that dryness and changes in water level and forest cover may have had a direct impact in human occupation, explaining the changes observed in the archaeological record. |
