+ - New Theory Explains Periodic Mass Extinctions

Submitted by i_like_spam

Asteroid impact theory does not apply to the other fluctuations in biodiversity, however, which follow an approximate 62 million-year cycle. As reported in Science news, a new theory seems to explain periodic mass extinctions. The new theory found that oscillations in the Sun relative to the plane of the Milky Way correlate with changes in biodiversity on Earth. The researchers suggest that an increase in the exposure of Earth to extragalatic cosmic rays causes mass extinctions. Here is the original paper describing the finding.
