One of the episode's most vividly told passages: Nehls describes a catastrophic African drought and ice age beginning roughly 200,000 years ago that reduced humanity to perhaps a few hundred survivors on the South African coastline. These proto-humans had unlimited access to shellfish — the perfect brain food. Mussels and other shellfish concentrate lithium 3-5 fold from seawater (which already has 100 times more lithium than freshwater) and are packed with omega-3 fatty acids. The result was a neurological revolution: the hippocampus grew, the mental immune system evolved, and Homo sapiens became the cognitively dominant species. The very site Nehls describes was designated a UNESCO World Heritage Site in 2024, lending unexpected institutional validation to his narrative. The lesson: we were built to eat shellfish, and moving away from coasts into cities and inland agriculture is when the lithium deficiency crisis began.
Seawater contains 100 times more lithium than freshwater, and shellfish concentrate it a further 3- to 5-fold, making them the ideal natural lithium source.
