ResumoFirst described over 120 years ago in Brazil, Amazonian Dark Earths (ADEs) are expanses of dark soil that are exceptionally fertile and contain large quantities of archaeological artefacts.The elevated fertility of the dark and often deep A horizon of ADEs is widely regarded as an outcome of pre-Columbian human influence 1 .Archaeological research provides clear evidence that their widespread formation in lowland South America was concentrated in the Late Holocene, an outcome of sharp human population growth that peaked towards 1000 BP 2-4 .In their recent paper Silva et al. 5 argue that the higher fertility of ADEs is principally a result of fluvial deposition and, as a corollary, that pre-Columbian peoples just made use of these locales, contributing little to their enhanced nutrient status.Soil formation is inherently complex and often difficult to interpret, requiring a combination of geochemical data, stratigraphy, and dating.Although Silva et al. use this combination of methods to make their case 5 , their hypothesis, based on the analysis of a single ADE site and its immediate surroundings
