FRACTAL WORLD. “Most cells, tissues, organs – in either the animal or vegetal worlds – are systems in which the component parts and unit fragments assemble with different levels of complexity and recursive organization at several orders of magnitude. This means that a single fragment or element may, on various scales, reproduce the whole object from which it is derived; in other words, it is self-similar, albeit in a statistical sense.”
