American archaeologists stated that ancient people used tobacco about 12 thousand years ago. The appropriate study is published on the site of the NATURE magazine, the SCIENCE NEWS portal reports.
The discovery was made during parking spaces in Utah, when experts studied the ancient hearth in the camp-collector camp. In it, they found traces of testing tobacco use as an intoxicating means. In particular, four charred tobacco seeds were discovered, which managed to dock by the radiocarbon method. According to scientists, it is 9 thousand years earlier than was considered before.
At the same time, scientists suggested that ancient people could not only burn tobacco, but also to chew his leaves and stems. According to the archaeologist from the group of anthropological research of the far west in Henderson, Nevada, Daron Duka, Nakhodka suggest that people used tobacco thousand years before the time when people first domesticated this plant.
Previously, Australian scientists from the University of Curtin found a new kind of wild tobacco. The plant produces a sticky substance for capturing and destroying insects.
