No such thing as a wilderness?

Some 40 authors are listed in the title of Persistent effects of pre-Columbian plant domestication on Amazonian forest composition in Science. The TL;DR is: The Amazonas Rain Forest is a 10.000 year old garden, which has been left untended for the last 500 years after the Amerindian genocide of European conquistadors.

The extent to which pre-Columbian societies altered Amazonian landscapes is hotly debated. We performed a basin-wide analysis of pre-Columbian impacts on Amazonian forests by overlaying known archaeological sites in Amazonia with the distributions and abundances of 85 woody species domesticated by pre-Columbian peoples. Domesticated species are five times more likely than nondomesticated species to be hyperdominant.

Across the basin, the relative abundance and richness of domesticated species increase in forests on and around archaeological sites. In southwestern and eastern Amazonia, distance to archaeological sites strongly influences the relative abundance and richness of domesticated species. Our analyses indicate that modern tree communities in Amazonia are structured to an important extent by a long history of plant domestication by Amazonian peoples.
