Human migration to new continents, islands, large and small mammals and birds. Overkill thesis, excessive predation, introduction of predators, competitors and disease vectors.

Correlation and cause don"t exist in martins"argument so it is flawed. No direct evidence for human hunting 50,000 years ago no evidence, sites, Africa and eurasia, co-evolution and fewer extinctions.
