Comet impact led to Ice Age extinctions: Study

Researchers have found further evidence to support the earlier theory that an extraterrestrial body such as an asteroid or a comet may have crashed into the Earth almost 13,000 years ago, and caused the extinction of many large animals, and a likely decline in early human population.

The study, published in the journal Scientific Reports, noted that an asteroid or a comet hit the Earth, or blew up in the atmosphere 12,800 years ago, causing a period of extreme cooling that may have led to the extinction of more than 35 species including giant sloths, sabre-tooth cats, and mammoths in what is called the Younger Dryas climate event.

The researchers, including those from the University of South Carolina (UofSC) in the U.S., found further evidence of a cosmic impact based on research done at White Pond near Elgin in the US.
