Probable reasons for the occurrence of comparable abstract and figurative designs in the art inventories of different ancient cultures since prehistory

It is assumed that some if not most abstract motifs that decorated internal house walls, shrines, stone and ceramic vessels, amulet-like objects, stamp seals and occasionally figurines in different prehistoric societies could well be enigmatic expressions of inherent spiritual notions. To explain the spiritual complexity of the human mind or mental mechanisms that designed such motifs and tried to preserve them in order to pass them onto new generations with their original or revised sacred notions that they expressed requires an interdisciplinary and multi-facetted scientific approach including neurophysiology which is well beyond the scope of traditional archaeology.
