A regular pattern of extinction of plants and animals on the earth can be correlated with which of the following?
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, started exploiting the surrounding environment and in turn made animals go extinct. Natural events like an asteroid strike, volcanic eruptions, etc do not show a regular pattern and cause mass extinctions. Thus, mass extinctions and man-made extinctions are different.
