Southpaw chimpanzees

A three-year study of 17 wild chimpanzees in Tanzania found that 12 of them used their left hands when using sticks to probe for termites.

Only four were right-handed, as one used both hands to dig out the ants.

The strange thing is, the researchers (from Emory University in Atlanta)reported a right-handed preference when the chimps cracked open nuts.
