Abstract
Due to neural plasticity, cortical areas can support “ectopic cognitions”. These are cognitions that exist in spite of no specific evolutionary preparation (sight on auditory cortex neural circuits; language upon visual cortex ones). First, their existence is inconsistent with evolution having selected genes to construct cognitions in the same manner that they construct complex body organs such as the eye. Second, their existence suggests that neural plasticity might itself have played an important – but so far – uninvestigated role in human origins. Three interrelated processes can be identified. (1) Human evolution by expanding brain size would have provided extra cortical space for neural plasticity to underlie nonevolved cognitions. (2) Human evolution by changing the body’s input and output capacities (articulate hands, bipedalism, vocal tract and breathing modifications) would have provided new types of information and control for the development of such cognitions. (3) Cultural processes, increased in complexity by these new cognitions, would then through their material, content (symbols), and motivational effects have led to the development of further nonevolved cognitive capacities. Thus, neural plasticity, rather than cognition constructive genes, could have provided the means by which evolution created complex human cognitions.
