The Remnants of Prehistoric Plant Pollen Reveal that Humans Shaped Forests 11,000 Years AgoThe discoveries could boost indigenous populations’ claims to ancestral lands long thought to be untouched by human activity
A tropical forest writes much of its history at large scale, producing trees as tall as skyscrapers and flowers the size of carry-on luggage. But by zooming in, scientists are uncovering chapters in forest history that were influenced by human activity far earlier than anyone thought.
A new study of pollen samples extracted from tropical forests in southeast Asia suggests humans have shaped these landscapes for thousands of years. Although scientists previously believed the forests were virtually untouched by people, researchers are now pointing to signs of imported seeds, plants cultivated for food, and land clearing as early as 11,000 years ago—around the end of the last Ice Age.
