A long-awaited, high-tech analysis of the upper body of famed fossil Little Foot opens a window to a pivotal period when human ancestors diverged from apes, new USC research shows.
Little Foot s shoulder assembly proved key to interpreting an early branch of the human evolutionary tree. Scientists at the Keck School of Medicine of USC focused on its so-called pectoral girdle, which includes collarbones, shoulder blades and joints. ....

Our bodies use less water than those of other primates

Water in, water out
The study compares the water turnover of 309 people with a range of lifestyles including farmers, hunter-gatherers, and office workers with that of 72 apes living in zoos and sanctuaries.
To maintain fluid balance within a healthy range, the body of a human or any other animal is a bit like a bathtub: “water coming in has to equal water coming out,” Pontzer says. Lose water by sweating, for example, and the body’s thirst signals kick in, telling us to drink. Chug more water than your body needs, and the kidneys get rid of the extra fluid. ....

Humans evolved to be the water-saving ape

E-Mail
DURHAM, N.C. When you think about what separates humans from chimpanzees and other apes, you might think of our big brains, or the fact that we get around on two legs rather than four. But we have another distinguishing feature: water efficiency.
That s the take-home of a new study that, for the first time, measures precisely how much water humans lose and replace each day compared with our closest living animal relatives.
Our bodies are constantly losing water: when we sweat, go to the bathroom, even when we breathe. That water needs to be replenished to keep blood volume and other body fluids within normal ranges. ....
