By charting these discrete patterns of neural excitation and inhibition, Oster and Ermentrout were able to build a mathematical model for shell formation that accounts for virtually any design observed in nature, from the zigzagging lines of Natica communis to the seemingly random patterns of mottled patches on a cone snail’s shell. “A single equation is sufficient to explain this tremendous diversity of patterns,” says Alistair Boettiger, a Berkeley graduate student who developed a computational modeling program for Oster and Ermentrout based on their findings.
