Did a magnetic field collapse trigger the emergence of animals?

A team of researchers from the University of Rochester has uncovered evidence that a weak magnetic field millions of years ago may have fueled the proliferation of life. The study suggests that fluctuations in Earth's ancient magnetic field led to shifts in oxygen levels, enabling more advanced life forms to emerge.
