Research results report that comet impact in prehistoric times led to a transition from hunter-gatherer society to agriculture

In the past, all humankind built

hunter-gatherer societies based on hunting and gathering animals and plants, but with the Neolithic Revolution (Agricultural Revolution) in the Neolithic Age, some societies became agrarian societies based on farming. has moved to. Research has reported that this transition from hunting and gathering to farming was caused by a comet impact that occurred approximately 12,800 years ago.

A research team led by geoscientist James Kennett from the University of California, Santa Barbara, studied the subglacial period called the Younger Dryas , which occurred from 12,900 to 11,500 years ago.

The research team supports the ``Younger Dryas Impact Hypothesis'' that the comet collided with the Earth's atmosphere, kicking up loose dust, resulting in dramatic cooling. In addition, we reported that evidence suggesting that the Younger Dryas brought major changes to the lifestyle of the inhabitants was found at the Syrian ruins of Tell Abu Hureyra, where evidence of humanity's oldest agriculture has been recognized.

Before the meteorite struck, Tel Abu Hureyra had a rich forest, and people practiced hunting and gathering. However, about 128 million years ago, when a meteorite collided with the earth, the earth suddenly cooled down, and the area around Tel Abu Hureyra changed to an arid climate with little nature.

Tel Abu Hureyra has already sunk to the bottom of the dam, but before it sank into the dam, archaeologists extracted various materials. Dating based on the deposited strata shows that in the pre-Younger Dryas period, when Tel Abu Hureyra was rich in nature, the residents ate wild legumes, grains, and fruits such as berries. I already know. However, in Tel Abu Hureyra during the period of cooling due to the Younger Dryas, fruits and berries disappeared from the diet, and lentils, barley, and wheat increased in their place.

This result suggests that the hunter-gatherer society of Tell Abu Hureyra came to a standstill due to the cooling caused by the Younger Dryas, and as a result shifted to the cultivation of grains and legumes. 'The evidence clearly shows that villagers started growing barley, wheat and pulses,' Kennett said.

Evidence pointing to a meteorite impact has been found all over the world, including in the Americas and Europe, and at Tel Abu Hureyra, a carbon-rich 'black mat' littered with diamonds, platinum and spheres of various metals was discovered.

geological formations have been discovered.

Black mats have also been found at nuclear test sites, including the Trinity test . The heat released by nuclear tests and the heat released by meteorite collisions both exceed 2000 degrees Celsius, which is enough to melt surrounding quartz and other materials.

Kennett said, ``When a meteorite decomposes at low altitudes and under high pressure and falls on Earth, the impact modification effect on quartz existing on the ground is essentially the same as the impact modification effect caused by a nuclear test explosion. ” states.

Regarding this discovery, the research team also said, ``During the transformation of human society and culture, including agricultural development, there was an impact from extraterrestrial sources such as meteorites, and the accompanying changes in the environment and climate, which had not been thought of until now.'' This suggests that there is a new causal relationship.'
