Darting lizards swing from four-legged to two-legged locomotion like a road bike popping a wheelie, a study published [Friday] in Journal of Experimental Biology suggests.
"It's a very interesting paper," said Duncan Irschick, a functional morphologist at the University of Massachusetts who did not participate in the research. "People have never understood why lizards run bipedally."
... [Christofer] Clemente and colleagues [at the University of Cambridge] filmed lizards running on a treadmill. "We showed that there tends to be this acceleration threshold -- there's this one acceleration where once the lizard hits it, it really has no choice but to go bipedal because the torque starts to move its head up," he said.

PODCASTS: Expanding With the Cosmos
Using the Atacama Cosmology Telescope (ATC), a 6.5-meter microwave collector in Chile, cosmologists are piecing together the early history of the known universe. In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.
