Scientists have discovered kelp off the coast of Ireland, Scotland and around Brittany in France that has survived since the last ice age around 16,000 years ago.

Experts from Heriot-Watt University’s Orkney campus, the University of the Algarve in Portugal and Station Biologique de Roscoff in France analysed the genetic composition of oarweed from 14 areas across the northern Atlantic Ocean.
