De Bestiarum Naturis 584 – il Ghiaia

The natural world is infinitely complex and hierarchically structured, with smaller units forming the components of progressively larger systems: molecules make up cells, cells comprise tissues and organs that are, in turn, part of individual organisms, which are united into populations and integrated into yet more encompassing ecosystems. In the face of such aweinspiring complexity, there is a need for a comprehensive, non-reductionist evolutionary theory.

(Niles Eldredge – 2016)


In qualità di animale non-immobile, il Ghiaia

è evolutivamente imparentato con il più famoso Pollicino, o Tom, e

con tutte le bestie litiche di cui si parla al DBN 644
