This thesis proposes hypothesis about the evolution of complex adaptive systems in the context of the interaction between society and the paleoclimate variability, based on comparative studies of bibliographic sources available in the literature: articles, research reports and data. The research was oriented in one cognitive and evolutionary perspective, subsidized by the complex geographical approach, structured by the author. Founded on archaeological evidence, the thesis argues that complex adaptive systems developed after 40 thousand years ago are between the main factors which cooperated in the social and cultural complexity, fixing on the territory, organizing large groups, the continuous pursuit of innovation and acceleration of cultural evolution and cognitive, established before the Holocene, as well as diversification of similar adaptive strategies in different parts of the world during this period; case of systematic collect, cultivation, domestication and agriculture. Between complex adaptive systems developed before the Holocene is cited: the science, the belief system, art, spoken language, symbolic communication, and the socio-political organization to manage large groups. Transferred by cultural exchanges, complex adaptive systems migrated with people, giving great adaptive differential to their carriers to favorable conditions in interglacial Holocene: an increase of temperature, humidity, rainfall, CO² in the atmosphere from 180 ppm to 280 ppm, and expansion the diversity and productivity of the species. Under non- linear processes, the successive period of intensification of innovation were associated with severe glacial and interglacial transitions of the 26 Dansgaard-Oeschger and Heinrich events (D-O and H), during the Würm Glacial, especially from 40,000 years ago, after “great leap” of modern humans. Based on the successes and failures of societies, imprevisibility and frequency of abrupt paleoclimatic changes, we present a proposal for Adaptive Sustainability Panel, focusing on three scenarios: global warming (Plan A), global cooling (Plan B) and climatic instability (Plan C), in order to increase the potential for proactive resilience in societies.
