KYOTO A team led by a Kyoto University researcher observing a group of western lowland gorillas in the wild found that about 70% of the mammals were right-handed.
The findings were published on Jan. 11 in the online edition of the American Journal of Physical Anthropology.

However, the discovery could contribute to existing theories on the human acquisition of a dominant hand.
