Crystals have been fascinating humans for hundreds of thousands of years, chimpanzees might share the same shiny object obsession, and mushrooms may be sending electrical signals through their underground networks. This episode bounces between ancient archaeology, animal behaviour, and the weird possibility that fungi are doing more than just quietly existing in the forest.

We dig into evidence that early humans collected crystals long before cave paintings, then look at research showing chimps will pick crystals over plain pebbles and carry them around like prized possessions. It is either a shared cultural quirk or a shared ancestor who also could not walk past a sparkly rock without grabbing it.

Then we head to Japan, where scientists have been measuring mushroom electrical activity with electrodes to see how fungi respond to things like water and chemical signals. It is not “mushrooms are speaking English”, but it does hint at complex, responsive systems in the mycelium that we are only just starting to understand.

Finally, we get into the modern tech mess: AI powered toys like teddy bears that can be prompted into wildly inappropriate conversations, plus a brilliant detour where medieval Japanese poetry helps researchers track solar proton events using tree rings.
