So basically what I didn't tell you is that about 500 million years ago, the organisms started making materials, but it took them about 50 million years to get good at it -- 50 million years to learn how to perfect how to make that abalone shell.
Så det jeg dybest set ikke fortalte jer er at for cirka 500 millioner år siden, begyndte organismer at lave materialer, men det tog dem cirka 50 millioner år at blive gode til det. Det tog dem cirka 50 millioner år at lære hvordan man perfektionerer det at lave abaloneskaller.
