Temporal variation of the diversity of terrestrial organisms has recently been put on the firm statistical basis. Rohde and Muller (Nature, 434, 208, 2005) have shown, using the de-trended data from Sepkoski's compendium, that the number of marine genera varies periodically with time with approximately 62 ±3-million-year period. No satisfactory explanation has been put forward so far. For instance, ``traditional'' explanations of the cycle by the Solar system passing through the galactic spiral arms or the galactic plane do not reproduce the correct phase and/or period. Here we argue that the modulated cosmic ray flux can naturally explain the observed periodicity in the fossil record. We present a physical theory, which based on the cosmic ray propagation in the galactic interstellar medium magnetic turbulence and the Sun's motion in the Milky Way.
