一个简单的模型出现的支柱在白蚁巢Deneublessly修改，包括几个额外的功能，打破了原来的模型的同质性：（一）对流气流，驱动分子的信息素沿着一个给定的方向;（二）净流量的个人在一个特定的方向;（三）一个明确的自我维持的信息素线索;和（iv）信息素模板，其代表持续散发信息素的蜂王的存在的效果。它表明，在某些条件下，支柱转化为墙壁或画廊或室，这种转变可能不会被驱动的白蚁的行为的任何变化。由于在不同的条件下，在个人水平上的相同类型的响应可以产生不同的模式，因为以前的建设修改当前的建筑条件，我们假设，巢的复杂性可以从一个形态发生过程，逐步产生多样性的历史依赖的结构展开。
A simple model of the emergence of pillars in termite nests by Deneubourg is modified to include several additional features that break the homogeneity of the original model: (i) a convection air stream that drives molecules of pheromone along a given direction; (ii) a net flux of individuals in a specific direction; (iii) a well-defined self-maintained pheromone trail; and (iv) a pheromonal template representing the effect of the presence of a queen that continuously emits pheromone. It is shown that, under certain conditions, pillars are transformed into walls or galleries or chambers, and that this transformation may not be driven by any change in the termites' behaviour. Because the same type of response at the individual level can generate different patterns under different conditions, and because previous construction modifies current building conditions, we hypothesize that nest complexity can result from the unfolding of a morphogenetic process that progressively generates a diversity of history-dependent structures.
