French geologists Arnold Rheshar and Pierre Escollet are claiming to have proof stones are living creatures which move and breathe. Stones do this very, very slowly, of course, which is why until Arnold and Pierre came along no one noticed it.
Or almost no one, for I distinctly remember as a small boy my grandfather taking me to his workshop and showing me an experiment he was conducting in which he had placed an assortment of stones in a row, and painted them green in order to observe any incremental growth or movement. My grandfather did not think rocks were alive in the animal sense, his theory was stones absorb particles from the air (which is not unlike the breathing Rheshar and Escollet describe) and thus gradually increase in size over time. He also thought rocks were capable of working their way up out of the ground, then slowly gravitating toward habitats rocks find pleasant, such as beaches.
Unfortunately my grandfather died before his experiment concluded, and his research notes were lost, and the painted green rocks were lost as well...or else they grew up and escaped.
