Nearly half a billion years ago, there was a huge explosion of species development on Earth, leading to a dramatic increase in animal biodiversity – but the true cause of this event remains a mystery.
In a new paper published Wednesday in Science Advances, scientists show that the event coincides with the largest documented asteroid disintegration in the asteroid belt in the last two billion years.
This collapse, which is caused by collision with another asteroid or comet, would spread huge amounts of dust into the solar system.
"The blocking effect of this dust could partially stop sunlight from reaching the Earth – leading to lower temperatures," study co-author Birger Schmitz, professor of nuclear physics at the University of Lund, writes in The Conversation . "We know that this included climate change from more or less homogeneous to the separation of climatic zones ̵

" Our results clearly show that huge amounts of fine-grained dust reached Earth shortly after the collapse, "Schmitz writes.
