For Tomasello, this two-step evolutionary path of macro ecological pressures impacting micro-level skills in representation, inferences and self-monitoring, does not hold because natural selection would see internal mechanisms. "Cognitive processes are a product of natural selection, but they are not its target. Indeed, natural selection cannot even "see" cognition; it can only "see" the effects of cognition in organizing and regulating overt actions." Ecological pressures would have put prior cooperative or mutualistic behaviors at such an advantage against competition as to create a new selective pressure favoring new cognitive skills, which would have posed new challenges, in an autocatalytic way.
