70% of wild gorillas in Japan-led study found to be right-handed The Mainichi
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.
Although there have been numerous reports on the dominant hand of tamed primates in zoos and other places on an individual basis, there have been few instances where analysis was conducted on a whole group living in the wild. According to the research team, the recent findings were the result of observing a specific group, and thereby cannot be used to conclude that gorillas are right-handed in general. However, the discovery could contribute to existing theories on the human acquisition of a dominant hand.
