" Our findings reveal that a functionally significant change in the AHR occurred uniquely in humans, relative to other primates, that would attenuate the response to many environmental pollutants, including chemicals present in smoke from fire use during cooking. " So we have some genetic tolerance to bad stuff created from cooking? Cool. This does, however, raise ever more questions about studying the effects of chemicals on rats and primates and drawing conclusions from that to human populations.
