Scientists made fake leaves and dropped them in water tanks to observe how different shapes move as they sink.

Shape and symmetry help determine where a leaf lands — and if the tree it came from can recoup the leaf’s carbon as it decomposes.

Two physicists from the Technical University of Denmark have found that leaf shape is a determining factor in the distance ...

"Data correlating shape and settling across a broad range of natural, mutated, and artificial leaves support the fast-leaf-hypothesis: Deciduous leaves are symmetric and relatively unlobed in part ...
