First ‘animal cells’ could have been created by viruses

When a virus infects a living cell, it hijacks and reprograms the cell to turn it into a virus-producing factory. Now scientists at the University of California have for the first time discovered just how extensive that reprogramming can be, effectively turning bacterial cells into animal or plant-like cells. This might even be how the cells of more complex organisms evolved in the first place.
