Early Human-Like Skeletons Are First Outside of Africa
Date:9/19/2007

earn a lot from craniums, full or even partial skeletons are necessary to fill in many of the gaps. That's why the new findings from Georgia are so important, the experts said.

The time period in which the four Dmanisi individuals -- three adults and one adolescent -- lived is called the Plio-Pleistocene age. "It's right around the time that we have the emergence and spread of the earliest members of the genus Homo," said Erik Trinkaus, a professor of physical anthropology at Washington University in St. Louis.

Members of the Homo genus gradually spread north and east of Africa beginning (as far as scientists can tell) about 1.8 million years ago. They spread relatively quickly, reaching Southeast Asia and Indonesia by 1.5 million years ago, Trinkaus noted.

And, according to the Dmanisi remains, their more human-like legs and feet may have helped get them there.

"Absolute hindlimb length of the Dmanisi hominins is greater than in australopiths and close to that of later Homo, including modern humans," wrote the Georgia team, which was led by David Lordkipanidze of the Georgian National Museum in Tbilisi. "This may reflect selection for improved locomotor energy efficiency," they explained.

Laitman agreed that it's no coincidence that Homo's spread was linked to their improved bipedal gait. The specimens "also show features of the transverse arch of the foot, the longitudinal arc of the foot, and a particular [movement] of the big toe" not seen before, he said.

And yet other parts of the specimens' skeletons lagged behind in terms of approximating modern humans. For example, their upper limbs fit into the Homo genus but retained some characteristics of australopiths, the researchers noted. The Dmanisi group was relatively small-statured, too -- about 5 feet tall and 100 pounds on average.

Most significant, their brains were only 600 to 775 cubic centimeters in
