The correct option is C Human migration
∙ Plants and animals show a regular pattern of extinction in the history of living organisms. Such a pattern can be well correlated with the pattern of migration of humans. Human populations, when migrated to new areas, start exploiting the surrounding environment and in turn make animals go extinct.
∙ Natural events like an asteroid strike, volcanic eruptions, etc., do not show a regular pattern although they cause mass extinctions. Mass extinctions and man-made extinctions are very different.
