@russellmillar7132 To add my two cents... in Hawaii there was a major mass extinction after people arrived. However, there's evidence that Polynesian rats, not hunting, were to blame.
On the Ewa plain of O'ahu, the loulu palm forest disappeared quickly after the first sign of human habitation (in the 1100s? I forget), but the amount of charcoal suggests a low human population, whereas rats may have reproduced into the billions in a few years. "A great gray wave" one author put it.
Birds that survived the first mass extinction then did quite well until more people came in the late 1800s with more invasive species (mosquitoes and avian malaria).
In modern times, a couple birds were harmed by hunting after the old kapu system was abolished, before modern game rules were invented. But most were victims of invasive species brought by humans, rather than hunting.
So I definitely do not favor the Overkill hypothesis, in general. However, the very existence of game laws throughout human cultures hints that it could happen at times.
