Early humans wiped out by climate change, research studies have found

Climate change wipes out primitive humans, a study has found that warns scientists that global warming could have more impact than previously thought.

The cousins ​​of Homo sapiens failed to adapt to the cold decade thousands of years ago, a new study argues, adding that they are at risk of extinction if temperatures fall below what they used to be.

The reasons for the disappearance of several species for the survival of Homo sapiens alone have been the subject of controversy among scientists, who speculated that the competition between species as well as the Earth’s changing climate played a role.

However, a new study published in the journal One Earth claims that failure to adapt to the migratory climate was the main reason for the loss of the three species because they were unable to cope with the cold conditions.

Shortly before they disappeared, Homo erectus, Homo heidelbergensis, and Homo neanderthallensis, commonly known as Neanderthals, all had a sudden change in their environment.

The team used climate modeling technology to simulate climate change five million years ago and compared it with fossil records to discover that conditions existed for all three that were particularly difficult to survive during the last known period of their existence.

Climate change was the “most likely candidate” for the first two victories and it matched the competition to wipe out Neanderthals on Hondo Sepiens, the paper said.

Homo erectus, thought to be adapted to the warm and humid climate of Southeast Asia, became extinct after the onset of the last glacier, extending this period from 11,000,000 to 11,000 years ago and making the Earth colder . Now

This may be the coldest time of the species, the paper says.

Neanderthals that died after the same period first disappeared from northern latitudes and this theory proves that they struggled to adapt to the cold climate.

Earlier, Homo heidelbergensis, often considered the ancestor of both modern humans and Neanderthals, died in the face of a struggle when they were unused in cold weather.

Pasquale Raya, top author of the University de Napoli Federico II magazine in Naples, Italy, said Neanderthals died after using clothing, fire and equipment.
