Humboldt University of Berlin research also shows Asian elephants have more wrinkles than African cousins

While humans are split between right-handers and left-handers, elephants have a preference for which side of their trunk they use. Now scientists have discovered it is possible to determine an elephant’s “trunkedness” by looking at its wrinkles.

While, overall, the pachyderms show an almost 50:50 split in terms of which way they prefer to bend their trunks, scientists have found it is possible to determine an individual adult’s preference.
