A comet strike around 13,000 years ago may have significantly influenced the course of human civilization, according to the Younger Dryas impact hypothesis. The comet strike is believed to have caused a global cooling event and the extinction of numerous large animal species. This theory, which became mainstream in 2007, is supported by evidence found in specific soil layers known as “black mats” and their geochemical signals. While some scientists dispute the hypothesis, no evidence has been found that directly contradicts it. It is still uncertain how this event may have affected the future of mankind.
Key Takeaways:
- A comet strike around 13,000 years ago is believed to have significantly influenced the development of human civilization by causing global cooling and the extinction of many large animal species.
- This theory, known as the Younger Dryas impact hypothesis, is based on distinctive soil layers and the geochemical signals found within them.
- While some scientists dispute this theory, no evidence has been found that definitively contradicts it.
“A consensus of evidence indicates that the progress of human civilization was aided by a comet strike approximately 13,000 years ago. The comet’s impact is believed to have caused global cooling and the extinction of many large animal species. The key to these findings lies with distinctive soil layers known as ‘black mats’ and the geochemical signals within them.”
