Cumulative evidence from archaeology and ethnohistory shows greater va
riety and complexity among Amazonian Indian societies of the prehistor
ic and contact periods than exist today. The ancestors of living India
ns traveled a long cultural history from early foragers who hunted wit
h fine stone points and made rock paintings, to innovative pottery-age
fisherpeople and horticulturalists, and finally to the populous, weal
thy, and powerful chiefdoms of late prehistory. This history was trunc
ated and impoverished when Europeans invaded and relegated Indians to
ecological and societal marginality.
