We demonstrate that a uniform cosmological seed field is a much less suitable seed field for a galactic dynamo than has often been expected. The age of the Universe is insufficient for a conventional galactic dynamo to generate a contemporary galactic magnetic field starting from such a seed, accepting conventional estimates for physical quantities. We discuss modifications to the scenario for the evolution of galactic magnetic fields implied by this result.
