Evolution of animal personalities studied
SANTA FE, N.M., May 31 (UPI) -- A team of U.S. and German scientists studying the evolution of animal personalities has found animals differ strikingly in character and temperament.
Although only recently has it become evident that personalities are a widespread phenomenon in the animal kingdom, scientists have already described personality differences in more than 60 species, including primates, rodents, birds, fish, insects and mollusks.
Now research led by Max Wolf of the German University of Groningen, who is now at the Santa Fe Institute, is offering an explanation of the evolution of animal personalities.
