Supernova explosions could have altered evolution on Earth
Astrophysicists have done a bit of crime scene investigation on what’s almost a reverse murder mystery. They’ve traced radioactive elements on the seafloor back to the cosmic explosions they might have come from – and potentially linked the event to evolutionary changes in viruses in a lake in…
They’ve traced radioactive elements on the seafloor back to the cosmic explosions they might have come from – and potentially linked the event to evolutionary changes in viruses in a lake in Africa. Currently, our solar system sits in the middle of a big empty patch of space called the Local Bubble, which is thought to have been blown by a series of supernova explosions 10 to 20 million years ago. Intriguingly, they found a paper that described how viruses in Lake Tanganyika in eastern Africa rapidly began diversifying into new species between two and three million years ago.
