Title: Proof that money does grow on trees Written by: duddy on Oct 23, 2013 (https://biology-forums.com/gallery/47/4_23_10_13_12_13_35.png) (https://biology-forums.com/index.php?action=gallery;sa=view;id=14225) Well, okay GOLD. Apparently, gold grows on eucalyptus trees. Researchers discovered that the trees are acting as a hydraulic pump, extracting gold from the soil and moving it to their leaves and branches. The ‘nuggets’ are about one-fifth the diameter of human hair, but the leaves may be used in combination with other tools to develop better exploration techniques. |
