A new study stated that the extinction of the largest well -known prime, a giant monkey from China, was caused by its struggle to adapt to environmental changes. These results block a major gap in our understanding of the reason for the failure of this species to survive despite the continuation of other similar main main leaders.
According to the study published in the journal Nature, the organism called Giganto is a type of upper monkeys that was found in China two million and 330 thousand years ago, and after that these species became extinct, as the statement of the study states.
The height of these monkeys reaches 3 meters and weighs between 200 and 300 kg, and it is believed that this object is the largest of the main main of the Earth ever.
The only extinct
Scientists believe that the giant Monkey Giganto is the only huge monkey that has become extinct in the most recent period on the Earth in the Pelistosini era. It is still present today.
After more than 85 years of research, archaeologists only found the teeth and four decoding bones that return to this extinct type. In the new study, the researchers collected a wealth of evidence, including fossils, quartz rocks, sediments, and pollen from 22 locations and cave through the Guangzhi Province in southern China, and they dated them using 6 different technologies.
“The rebuilding of an extinction event like this is a rare achievement in excavation science and requires accurate history, in the case of extinction it is related to it All of the timing, and if you do not have a suitable timing, you are only looking for evidence in wrong places or you only look at very long time periods. ‘
To determine the history of each site, researchers used history techniques, such as measuring the amount of uranium that fossils absorbed over time, or the optical signal that the quartz launched in the soil when it was detonated by laser. These results provided scientists dates that occurred in the narrow window between 295 thousand and 215 thousand years.
“We wanted to be very accurate so that we can look at what the environment was at that time,” Westway added. Unfortunately, the environmental records are not already very detailed, so we also prepared the building of the environment in which the giant monkeys lived using pollen, the analysis of the very detailed deposits, and the isotope analyzes in the monkey’s teeth
The virtual construction of the old environmental conditions resulted in a perception due to nearly 2.3 million years. The giant monkey’s home is a vibrant forest with mosaic of trees and herbs, where the ‘jungle’ person and ‘giganto’ lives and they flourish together in this forest environment.
But the scene has changed radically before the extinction of giant monkeys between 600 thousand and 300 thousand years. One day, it was a thick cover of forests, it became open, open to fern and herbs. And one day it was a comfortable climate with its favorite food and water throughout the year, it is now unstable as the water is limited to the rainy season only.
The researcher participating in the study explained that this unstable environment placed the ‘Giganto’ under tremendous pressure due to the magnitude of its size and the difficulty of moving it over long distances, while the ancestors of human beings succeeded in moving to other sites in search of food.
The researcher warns of signs of sixth extinction that threatens the current monkey environments as a result of the acceleration of forest removal rates and the worsening effects of climate change.
