How is modern living changing our feet?

An evolutionary biologist explains why our feet have become larger, flatter and weaker
The industrial revolution changed everything. It brought innovation and technology, but also a physical cost to our bodies.

From spending hours on our bare feet outdoors, many of our jobs suddenly moved indoors where we began to sit down at desks in offices and drove cars. We also began to wear shoes.

Dr Vybarr Cregan-Reid talks to evolutionary biologist Dan Lieberman at Harvard University, on how our lifestyles and what we wear have changed our feet forever.

A handwritten draft of Charles Darwin's On the Origin of Species has been placed under an export ban as attempts are made to find £490,000 to keep it from leaving the UK.

The page from Darwin's landmark work includes corrections and shows his reworking.

The ban also includes two pages from another of his works and the three's combined value is more than £800,000.

Darwin, who was born in Shrewsbury in 1809, came up with the theory of evolution by natural selection which explained how new species evolved.

Minister for Heritage Michael Ellis said he placed the temporary ban on the pages as they "create an incredibly powerful impression".

The application licence has been deferred until 7 May and could be extended to 7 September if "serious intention" is shown to raise the money.
