A new study discovered that the ancient humans lived in the tropical rainforests before we thought first.
Before now, the nearest evidence of humans (Hoomo, the sane) Live in rain forest environments dated 70,000 years ago In Asia and Oceania only 18,000 years ago In Africa.
Now, according to a new study published on Wednesday (February 26) in the magazine natureThe researchers have found evidence that humans lived in areas similar to rainforests in Africa 150,000 years ago.
“Our results are pushing back in the oldest known presence of human beings in the tropical forests with more than twice the estimate of the previously established in another region of the world as well as in Africa.” Eslem ben ArousA researcher at the Max Planck Institute for Geographic Science in Germany said to life science in an e -mail.
Modern people have evolved from our ancestors in Africa 300,000 years agoAccording to the oldest known H. The sane The excavations, which were found in Jabal Iron, Morocco. Others discovered in Ethiopia to About about 200,000 years ago. However, these were found in areas that are believed to have herbal lands at the time of the ancient human population.

In the eighties of the last century, researchers discovered stone tools, such as shots, and were buried in depth underground at a site called Bété I on Ivory Coast in West Africa. But at the time, they were not able to the history of the stone tools, according to statement. Now, with the emergence of new technologies, such as The shine is visually stimulatingAnd that enables researchers to know when things were the last time of the heat of the sun, the researchers enabled the history of the tools 150,000 years ago.
Moreover, the team revealed the effects of the old plants of rainforests, providing new visions in the wet environments in which these old human beings live.
“Our strong study showed the existence Hunter Oil palm, they are typical varieties [a group of organisms] For this ecozone and that [of] Bin Arz explained, a wet tropical forest.
Nowadays, the southern Ivory Coast is a tropical environmental system in the rainforest, but so far, it was not clear whether it was still a tropical forest wet 150,000 years ago.
These discoveries indicate that environmental -like environments were not an obstacle to human expansion, and instead they were inhabited hundreds of thousands of years ago. In addition, the presence of such ancient human artifacts supports in this theoretical region Hoomo, the sane Perhaps I grew up in multiple places throughout Africa, instead of all grew up in one location and spread abroad.
“We know that humans did not have one” hometown “in Africa. However, it is currently unclear whether we look at humans who develop in herbal and savanna lands in Africa, or whether there are a number of different environments.” “Our results indicate that we are looking at the last scenario.”
Bin Arz also suggests that the ancient human beings who were adapted strongly with live in rainforests have often not faced people who were adapted to live in open herbal lands.
In 150 thousand years, it is the oldest known site in West Africa and shows that people have lived in this region at least BlastoceinBin Arous said: This is important because before our work, it was believed that the record of West Africa was younger. “
