The Story of a Foot

In today’s issue of the journal Nature a new discovery is detailed – the partial remains of a foot of belonging to a hominid that lived between 3 – 4 million years ago. Not only did it walk upright but it could climb trees too. Amazing.

How do they know?
Its big toe is set apart from the rest of its foot, allowing it to grip tree branches, and it had no arch. There are signs in the bones and joints that it walked on two legs.

Over the past millions of years, the human foot has changed to give us a springy step. We have a stout big toe that lines up with the other toes. We also have a stable heel and an arch that distributes our weight when we walk, run or jump according to William Harcourt-Smith of the American Museum of Natural History in New York

‘This find is the first good evidence that there was a second, different species lineage’ at that time, said Tim White, director of the Human Evolution Research Center at the University of California, Berkeley

There are many branches to this large tree!
