UT researchers figuring out what's behind penguin waddle

KXAN News - AUSTIN (KXAN) -- Researchers from the University of Texas are joining English scientists to figure out what's behind nature's strangest stride: the penguin waddle. Penguins stand up tall like humans but have short legs. The researchers are studying the flightless birds at the London Zoo using a running track with sensors to measure the individual movements.

UT Ph.D student James Proffitt says this research will show how the penguins evolved -- and maybe explain why penguin species vary so much. Proffitt is working with John Hutchinson of London's Royal Veterinary College.

"The biologists set up a kind of corridor, a long wooden platform with Lucite walls, and began fitting it with metal force plates-two small, about the width and length of a shoebox, and one large, about three times bigger," says The Jackson School of Geosciences website. "'They're like fancy 3-D bathroom scales,' Hutchinson told me, designed to measure force side to side, front to back, and downward."
