Indigenous peoples in the Amazon have not exterminated a single species for thousands of years – Earth – Science and Technology

The ancient indigenous inhabitants of the Amazon were able to live in the rainforest for thousands of years without destroying even a single species or changing the composition of plants in any significant way.

This follows a new scientific study whose authors examined the development of three sites in Peru over 5,000 years. The analysis of microscopic fossil seed residues in the soil concluded that the former inhabitants of the Amazon were able to adapt to the environment and did not carry out any activity, on the contrary.

A study of a group of biologists published in a professional periodical Proceedings of the National Academy of Sciences (PNAS) provides evidence that some of the ancient inhabitants of the Amazon lived in the rainforest sustainably and did not interfere in any way.

However, other research has shown in the past that part of the indigenous population, on the other hand, intensively transformed the environment around them. According to them, for example, some species of trees that now dominate the Amazon were planted in prehistory by humans.

A detailed survey of the soil in three places in northeastern Peru, according to scientists, shows that the locals lived in symbiosis with the environment, because the composition of plants there has not changed over the centuries.

Research leader Dolores Pipern said her team deliberately focused on locations far from the banks of the rivers, where the fertility of the ancient population was more intense due to the fertile soil.

“We do not want to claim that the continued settlement of the Amazon had no effect on the landscape in some regions, but our study provides more evidence that the great changes that were the work of indigenous peoples took place mainly in fertile river areas and the use of the surrounding rainforest. sustainable and has not caused any observable loss of species for thousands of years, ”said Pipern.
