David Attenborough - 08/08/2009

This is the story of Archaeopteryx, the missing link between reptiles and birds and the fossil that provided evidence for Darwin’s theory of evolution.

Sir David Attenborough recalls the discovery of a feather, which, like any other we’re familiar with, has a central shaft and interlocking branches to trap air.

It was found in Germany, dated to a time in earth's history when birds had not evolved.
