Chimpanzees shed
light on origins of human walking

Summary:

Scientists investigating human and chimpanzee locomotion have uncovered
unexpected similarities in the way the two species use their upper body during
two-legged walking.

........................

A research team led by Stony Brook University investigating human and
chimpanzee locomotion have uncovered unexpected similarities in the way the two
species use their upper body during two-legged walking. The results, reported
inNature Communications, indicate that our
early human ancestors, including the famous fossil 'Lucy' (a species known as
Australopithecus afarensis), may have been able to use their torsos to increase
walking efficiency in the same way as modern humans.

The torso (the part of the body that includes the ribcage, belly and
pelvis) of chimpanzees has long been thought to be a rigid block, best suited
for a life of tree climbing. Humans, on the other hand, have long and flexible
torsos that aid in walking by allowing us to rotate our upper body in the
opposite direction of our lower body. The findings from the paper, titled
"Surprising trunk rotational capabilities in chimpanzees and implications
for bipedal walking proficiency in early humans," changes the evolutionary
view of how early human ancestors walked and what they were able to do.

"During walking, we actually observed as much rotation within the
torsos of chimpanzees as in humans," said Nathan Thompson, lead author and
a PhD student in the Department of Anatomical Sciences at Stony Brook
University. "This means that the widely accepted assumptions in the
scientific community about how the chimpanzee torso works based on the skeleton
alone are incorrect. Our results also point to the notion that a limitation to
upright walking that we thought affected Lucy and other early human ancestors
probably was not a limitation at all."

The research team used high-speed cameras to track and compare how the
torsos of humans and chimpanzees actually moved during bipedal walking. They
studied the movements by way of three-dimensional kinematic analyses and
computer-generated comparisons.

They discovered that the main difference between human and chimpanzee
bipedalism is that chimps swing their hips much more.

"Only when our early ancestors were able to reduce this hip rotation
were their upper bodies able to play a human-like role in promoting efficient
bipedal walking," said Thompson. "When this actual transition
occurred is still an open question."

There is a continuing debate about how the hips of our ancestors worked
compared to ours.

"For instance, depending on who you ask, the 3.2 million-year-old Lucy
fossil either rotated her pelvis exactly like modern humans or up to 2.5 times
more," he explained.

Given this uncertainty, the research team modeled the transition from a
more chimp-like pattern of the upper body movement to that of a more human-like
pattern. They found that even if Lucy rotated her pelvis 50 percent more than
modern humans, her upper body would have functioned essentially like ours. This
means that even as early as 3.2 million years ago Lucy might have been able to
save work and energy in much the same way as humans do today.

"As we get a better idea of how our closest living relatives move, we
are able to learn much more about the isolated piles of early human bones that
the fossil record leaves us," added Thompson. "Only then can we paint
a complete picture of how we evolved into what we are today."

Co-authors on the paper include Susan Larson, Brigitte Demes, and Nicholas
Holowka of Stony Brook University, and Matthew C. O'Neill of the University of
Arizona.

The research was funded by the National Science Foundation and The Leakey
Foundation.
