Controversial theory claims life on Earth was seeded by alien viruses

Roughly 540 million years ago, life on Earth changed dramatically; the planet, once dominated by simple organisms, suddenly became home to most of the major animal groups known today.

Before about 580 million years ago, most organisms were simple, composed of individual cells occasionally organised into colonies. A recent study linked the historic rise in oxygen responsible for the formation of animal life on Earth to fossil fuels. But, ‘the main statement about viruses, microbes and even animals coming to us from space, cannot be taken seriously.’
