It’s hard to know what decisions to make – or even to know what options we have.

Currently, we are faced with an enormous array of choices about how to move forward in a way that will enable our species to survive.

Examples include (left to right) mobilization of ancient terra preta (anthropogenic dark earth) technology, revitalization of landesque capital (long-term landscape investments) and adoption of traditional fire management regimes. “A lot of environments…have been managed for so long that it would be almost counterproductive to try and revert them back to their pre-human ‘natural’ state.” Around the world today, we can find many examples of how past cultural and technological practices and solutions are being revived to address pressing environmental and land management challenges.
“At what point in time do we say that a system has been modified by humans and is today a relic of centuries of human impact, versus something that is purely natural and pristine? “What is the pristine environment that should be conserved today?” she asks. Crowther – who specialises in archaeobotany – gives the example of the complicated choices we face around conserving ecosystems. Although the rate, scale and nature of changes is vastly accelerated today, humans have been transforming ecosystems for tens of thousands of years – recent research shows, for example, that forests in Malawi, Africa, have been modified by humans for at least 85,000 years.Ī deeper, more profound understanding of human history may shed light on how our current problems came about – and inform how to manage them. A long history of human impactĪrchaeology, the authors say, can place our current problems into a deep time perspective. This is the argument that Crowther and one of her colleagues, Nicole Boivin from the Max Planck Institute for the Science of Human History in Germany, put forward in a recent article published in Nature Ecology and Evolution. It may even equip us with the knowledge to move into the Anthropocene: the era in which humans have become shaping forces of nature, dominating the Earth’s systems on unprecedented scales. Instead, archaeology’s long-term view of human history can provide a degree of historical perspective and help us understand how we arrived at the present. “At what point in time do we say that a system has been modified by humans and is today a relic of centuries of human impact?“ “We’re no longer treasure hunters looking for lost cities and gold masks and Tutankhamun’s riches,” says Crowther, who works at the University of Queensland. According to Australian archaeologist Dr Alison Crowther, the discipline of the past has transformed over the last century and is now gearing up to tackle the problems of the future. Perhaps unsurprisingly, this picture of archaeology is now out of date. And in part, it is meant to show the nonreductive relations between the concerns of anthropologists and a variety of allied disciplines: linguistics and psychology, cognitive science and computer science, and evolutionary biology and complexity theory.The word ‘archaeology’ conjures one of the greatest opening scenes in film history: a whip-toting Westerner sprinting through an abandoned temple in the South American jungle, leaping across bottomless pits, sliding under closing doors, evading a massive boulder – all in the line of archaeological duty to retrieve a golden idol. In part, it is meant to meaningfully reframe the relations among the linguistic, biological, cultural, and archeological subfields of anthropology. And it develops the consequences of such conjunctions for various domains at various scales ranging from biosemiotic processes such as animal-signal systems and natural selection to technocognitive processes such as lawn mowers and Turing machines. It theorizes codes in conjunction with channels and thereby links shared cultural representations and networked social relations. It treats processes of significance and selection in conjunction with processes of sieving and serendipity and thereby systematically interrelates the key factors underlying emergent forms of organized complexity. This essay theorizes significance in conjunction with selection and thereby provides a general theory of meaning.
