Ape like feet found in study of museum visitors

RATE THIS! +9

A team studied the feet of 398 visitors to the Boston Museum of Science. The results show differences in foot bone structure similar to those seen in fossils of a member of the human lineage from two million years ago.

 

 

It is hoped the research, published in the American Journal of Physical Anthropology, will establish how that creature moved.

 

Apes like the chimpanzee spend a lot of their time in trees, so their flexible feet are essential to grip branches and allow them to move around quickly - but how most of us ended up with more rigid feet remains unclear.

 

Jeremy DeSilva from Boston University and a colleague asked the museum visitors to walk barefoot and observed how they walked by using a mechanised carpet that was able to analyse several components of the foot. Most of us have very rigid feet, helpful for stability, with stiff ligaments holding the bones in the foot together.

 

When primates lift their heels off the ground, however, they have a floppy foot with nothing holding their bones together.

 

This is known as a midtarsal break and is similar to what the Boston team identified in some of their participants.

 

This makes the middle part of the foot bend more easily as the subject pushes off to propel themselves on to their next step. Dr DeSilva told BBC News how we might be able to observe whether we have this flexibility: "The best way to see this is if you're walking on the beach and leaving footprints, the middle portion of your footprint would have a big ridge that might show your foot is actually folding in that area."
