Troll "Eden" discovered! (w/poll)

LONDON (AFP) - The discovery of a Turkish family that walks on all fours could aid research into the evolution of humans.

Researchers believe the five brothers and sisters, who can walk naturally only on all fours, may provide new information on how humans evolved from four-legged hominids to walk upright....

The siblings, the subject of a new BBC documentary to be aired on March 17, suffer from a genetic abnormality that may prevent them from walking upright.

Instead, they use their palms like heels with their fingers sticking up from the ground....Two sisters and one son have only ever walked on two hands and two feet, while another daughter and son occasionally walk on two feet.

All five are mentally retarded and have problems with language as a result of a form of underdevelopment of the brain known as cerebellar ataxia.
