“Radiation From an Exploding Star May Have Altered Evolution on Earth”

If a star explodes in space and no one is around to see it, does it wreak a change on terrestrial evolution?
Yes, maybe – if you’re a microbe quietly minding your own business in Lake Tanganyika in the highlands of eastern Africa.
A new study has found that an explosion in virus diversity 2.5 million years ago in Lake Tanganyika occurred at the same time radiation from an ancient supernova bathed Earth in cosmic rays.
