The advocators of Darwin’s theory of evolution discover that it is difficult for normal evolution rate alone to form the species diversity now. What factor(s) accelerated the origin of life and species diversity? Reference viewpoints: Novae, especially supernovae, would generate high energy cosmic rays that would impact on acceleration of creature DNA gene mutation during this period, thus create lots of new species. The best supernova rate estimate we can offer indicates that one or more supernova explosions are likely to have occurred within 10 pc or so of the Earth during the Phanerozoic era, i.e., during the last 570 million years since the sudden biological diversification at the start of the Cambrian.
