⏱️ 7 min read

Overview

Hannah Fry and Michael Stevens explore the lost prehistoric land of Doggerland that once connected Britain to continental Europe, examining how it disappeared beneath the North Sea around 8,000 years ago. They then delve into fascinating discussions about the evolution of 'coolness' as a cultural concept, the science behind 'stank face' reactions to heavy music, and share their current reading recommendations.

The Discovery of Doggerland Through a Mammoth Bone

Hannah presents Michael with a mysterious object from her French holiday - a mammoth vertebrae dredged from the North Sea. This fascinating artifact serves as the entry point to discussing Doggerland, a prehistoric landmass that connected Britain to Europe. The bone's discovery underwater reveals the hidden history of a land that disappeared into the sea, where mammoths once roamed freely between what is now the UK and continental Europe.

  • Hannah brings Michael a mammoth vertebrae from France, challenging him to identify it
  • The bone is identified as being from a land mammal bigger than an elephant - a mammoth
  • The mammoth vertebrae was dredged from the bottom of the North Sea
  • This discovery leads to discussion of Doggerland, the lost land connecting UK to Europe
" It's a mammoth vertebrae. Whoa, a vertebrae. Isn't that cool? That's so cool. "

Uncovering Doggerland's Existence

The discovery of Doggerland began in the 1930s when fishermen regularly brought up prehistoric remains in their nets, including mammoth bones and reindeer antlers. A crucial breakthrough came when sharpened reindeer horns were identified as human tools, and the surrounding mud was tested and found to be freshwater rather than saltwater. The oil and gas industry's 3D seismic surveys in the late 1990s and early 2000s finally revealed the detailed terrain of hills, valleys, and estuaries beneath the North Sea, proving this was once abundant forest land.

  • Fishermen had been bringing up mammoth bones and reindeer antlers for generations
  • In the 1930s, sharpened reindeer horns were identified as human tools
  • Testing revealed freshwater mud from the bottom of the salty sea
  • A Neanderthal skull aged 50,000-70,000 years old was found in Dutch beach deposits
  • Oil and gas industry 3D seismic surveys revealed detailed terrain with hills, valleys, and forests
  • Evidence showed oak, elm, and hazel forests once grew in Doggerland
" We're talking really recent that Doggerland disappeared into the sea. When? We'll get there. But really recently. "
