Britain is experiencing the same decline as Rome in 100BC, with the collapse of civilisation inevitable, a scientist has warned.
Dr Jim Penman, of the RMIT University in Melbourne, believes Britons no longer have the genetic temperament to advance because of decades of peace and a high standard of living.
He claims that the huge success of the Victorian era will not be repeated because people in the UK have lost the biological drive for innovation.
Instead, Britain is existing in a period similar to the decades before the fall of the Roman Republic where social tensions were rife, the gap between the rich and poor was increasing and extremism was growing.
And when added to a growing distaste for military action, which has seen huge cuts the armed forces, by the end of the century the UK will no longer have the power, or will, to protect itself against a serious invading force, he predicts.
