Images, details, and modeling the markings on the ostrich shells. Decembrini et al.\u00a0<\/a><\/p>\nA visual grammar in embryo<\/p>\n
In an intriguing new study funded by the University of Bologna, researchers gathered 112 marked fragments of water containers from two archaeological sites in South Africa. They showcased how even the simplest forms reveal extremely complex mental operations by reconstructing the lines, angles, and trajectories in detail. <\/p>\n
Through geometric and statistical analysis, the team concluded that 80% of the configurations displayed coherent spatial regularities. The use of parallel lines, angles close to 90 degrees, hatched bands, grids, and diamonds showcases cognitive operations of rotation, translation, repetition, and \u201cembedding,\u201d or the ability to build hierarchical levels of signs within the same surface.<\/p>\n
These engravings demonstrate a \u201cmastery of geometric relationships,\u201d according to Ferrara. Not only did they repeat signs, but rather they could conduct \u201creal visuo-spatial planning, as if the authors already had an overall image of the figure in mind before engraving it.\u201d<\/p>\n
These humans were not randomly sketching; rather, they repeated the same mental operations across different shells. The study even highlights the intricate mental processes involved in the simple act of lifting an arm to draw\u2014an action that requires conscious intention, subconscious planning, and motor execution.<\/p>\n
In several cases, as per Archaeology News<\/a>, the mind behind these symbols laid out a basic framework before \u201criffing\u201d on the idea, visualizing the final product before producing it.<\/p>\n The cognitive processes behind adaptation <\/p>\n Far from being rudimentary, the study investigated the neural mechanics behind these visual representations, suggesting the presence of abstract thought\u2014a crucial step in the evolution of human thinking<\/a>.<\/p>\n Notably, by the time Homo sapiens left Africa, they already possessed a remarkable ability to organize visual space and transform simple forms into complex systems.<\/p>\n \u201cTransforming simple forms into complex systems<\/a> by following defined rules is a deeply human trait that has characterized our history over millennia, from the creation of decorations to the development of symbolic systems<\/a> and, ultimately, writing,\u201d study author Valentina Decembrini stated in a press release.<\/a><\/p>\n This specific ability to construct and manipulate symbols reflects the cognitive plasticity that enabled Homo sapiens to adapt and thrive, as per IFLScience<\/a>.<\/p>\n
