New evidence supports the theory that a comet explosion over North America around 13,000 years ago caused widespread destruction, leading to the extinction of mammoths, mastodons, and the disappearance of the Clovis culture, by triggering fires, climate cooling, and environmental collapse.
Recent observations suggest that interstellar comet 3I/ATLAS has not exploded or broken into pieces, contrary to some claims, and most scientists agree it is a natural object from beyond our solar system, despite speculation about its origins.
Scientists found evidence of a comet explosion 12,800 years ago in ocean sediment cores from Baffin Bay, including microspherules and impact-related materials, supporting the hypothesis of a global impact event that may have caused the Younger Dryas cooling period.
A new analysis of remains from the now-extinct village of Abu Hureyra in northern Syria suggests that a large comet explosion 12,800 years ago led to the shift from hunting to agriculture and control of wild animals. The explosion, known as the Younger Dryas Impact Hypothesis, caused shockwaves that wiped out the settlement and triggered a change in climate. Before the event, the settlers consumed wild fruits, berries, and legumes, but afterward, their diet shifted to grains and lentils. The findings support the hypothesis that multiple comet airbursts occurred across continents during this time period.
A team of scholars has refuted the claim that a comet explosion 1,500 years ago led to the decline of the ancient Indigenous Hopewell culture, finding the evidence to be inadequate and inconsistent. The researchers identified no catastrophic event or decline in the culture, and noted possible intentional data manipulations in the original research. They concluded that the presence of meteorites and other materials claimed to be associated with a comet explosion were likely brought to the Hopewell sites for ceremonial purposes, and that the cultural shifts observed in the Hopewell culture were due to changes in social and religious practices.
