Much evidence supporting both theories has been presented but the acceptance of a super meteor wiping a selected species from the face of the earth is a leap of faith at best.
支持这两种说法的证据已提出了许多，但接受超级小行星的撞击而从地球表面选择性地抹去某些物种的观点，的确是一个观念上的飞跃。
This happened in 1998 when a so-called "super el Nino" helped heat the Earth to a record high.
