Scientists on Wednesday said dust spawned by a gigantic collision in the asteroid belt between Mars and Jupiter 400 million years earlier triggered an ice age on Earth that ushered in a significant increase in marine biodiversity.
The inner solar system was filled with enormous amounts of dust after an asteroid more than 90 miles in diameter was struck by a smaller object perhaps 12 miles wide, the researchers said. It was the solar system’s largest-known breakup event in the past 2 billion years. Another cooling mechanism was that the iron-rich meteoritic dust fertilized large parts of the ocean surface leading to increased plankton productivity and drawdown of atmospheric carbon dioxide, added Birger Schmitz, a geology professor at Lund University in Sweden and lead author of the research published in the journal Science Advances.
After noting the dinosaur-demise event caused by an asteroid perhaps 6 miles wide, Schmitz added, “For the first time, scientists can now present another example of how an extraterrestrial event formed life on Earth.”
No...our Dna was stolen
The world is not that old and no it was not by accident.
Not true
Order does not come by accident
Based on a lot of assumptions, making this a relative truth but absolute truth still waits to be discovered
