Possible mechanisms of pattern formation in biological systems include the classical reaction–diffusion model proposed by Alan Turing and the more recently found elastic instability mechanism which is thought to be responsible for the fold patterns on the cerebral cortex of higher animals, among other things.

生物系统中可能存在的斑图生成机制有阿兰 · 图灵Alan Turing提出的经典反应扩散模型和最近发现的弹性不稳定机制，该机制被认为是高等动物大脑皮层上褶皱模式等形成的原因。
Bacterial colonies show a large variety of patterns formed during colony growth. The resulting shapes depend on the growth conditions. In particular, stresses (hardness of the culture medium, lack of nutrients, etc.) enhance the complexity of the resulting patterns. Other organisms such as slime moulds display remarkable patterns caused by the dynamics of chemical signaling.

细菌菌落在生长过程中形成的形态种类繁多，其形成的形状取决于生长条件。特别是，培养基的硬度、营养物质的缺乏等外部压力增强了所产生的模式的复杂性。对于其他生物，如粘液霉菌等，则显示出由化学信号动态引起的显著模式。
