Ancient man walked, but struggled to run.

The studies show that “whilst these very early fossils could walk well, our initial findings suggest that efficient running came about quite a bit later in the fossil record,” he said, adding “we have only just started to look at running and so there are still plenty of questions to answer.”

Funny, I wouldn’t think that a fossil could walk at all…

“The next really interesting question is to look in more detail at running. It has been suggested that our ability to run for long distances took a lot longer to evolve than our ability to walk. Our techniques should let us get to the bottom of this question because it will let us measure the running abilities of our fossil ancestors directly.”

“What we need to discover now is when in our evolution did we develop an Achilles tendon as knowing this will help unravel the mystery of our origins.”

Well, at least I do have an Achilles tendon.
