Unscramble the Blue Letters

How can you make eenss of this? Well, we believed — and we hypothesized — that one way animals could orwk ylmips, is if the control of their movements tended to be built into their bodies themselves. What we discovered was that two-, four-, six- and eight-legged nimaasl all produce the same forces on the ground when they move. They all work like this kangaroo, they bounce. And they can be modeled by a spring-mass system that we call the spring mass system because we're biomechanists. It's actually a pogo stick. They all produce the pattern of a pogo stick. How is that retu? Well, a human, one of your legs works like two legs of a trotting dog, or works like three slge, together as one, of a trotting insect, or four legs as one of a trotting crab. And then they alternate in their opnosplrui, but the patterns are all the same. Almost every organism we've looked at this way — you'll see next week, I'll give you a hint, there'll be an article coming out that says that really big things like T. rex probably couldn't do this, but you'll see that next week.

Original Text

How can you make sense of this? Well, we believed — and we hypothesized — that one way animals could work simply, is if the control of their movements tended to be built into their bodies themselves. What we discovered was that two-, four-, six- and eight-legged animals all produce the same forces on the ground when they move. They all work like this kangaroo, they bounce. And they can be modeled by a spring-mass system that we call the spring mass system because we're biomechanists. It's actually a pogo stick. They all produce the pattern of a pogo stick. How is that true? Well, a human, one of your legs works like two legs of a trotting dog, or works like three legs, together as one, of a trotting insect, or four legs as one of a trotting crab. And then they alternate in their propulsion, but the patterns are all the same. Almost every organism we've looked at this way — you'll see next week, I'll give you a hint, there'll be an article coming out that says that really big things like T. rex probably couldn't do this, but you'll see that next week.
