Motion, muscles don't always work in lockstep, researchers find in surprising new study

Animals 'do the locomotion' every day, whether it's walking down the hall to get some coffee or darting up a tree to avoid a predator. And until now, scientists believed the inner workings of movement were pretty much the same. But in a first-of-its-kind study on wild green anole lizards, biologists have discovered that the link between muscle function and movement is a lot more complicated than anyone realized.
