摘要

Relationships between primates and snakes are of widespread interest from anthropological, psychological, and evolutionary perspectives, but surprisingly little is known about the dangers that serpents have posed to people with prehistoric lifestyles and to nonhuman primates. Here, we report ethnographic observations of 120 Philippine Agta Negritos when they were still pre-literate hunter-gatherers. Twenty-six percent of adult male respondents had survived predation attempts by reticulated pythons, and between 1934 and 1973, there were six fatal attacks on members of the group. Moreover, Agta ate pythons as well as three other animal species taken by the snakes, and therefore, people and pythons were reciprocally prey, predators, and potential competitors. These findings, combined with observations of snake interactions with nonhuman primates and interpreted within the context of snake and primate phyloge-nies, corroborate the hypothesis that complex ecological interactions have long characterized our shared evolutionary history.
