Mr Kajanga Kulatunga, presented a very intriguing analogy about the behaviour of slime mold. Before we go any further, let us tell you that slime mold is the green thing that grows on walls, especially during the rainy season. For centuries, scientists have been baffled by the mysterious behaviour of slime mold. It is said that when food is available in ample, the cells of slime mold operate as single-celled units. However, when food is scarce, slime mold cells come together to form clusters. In other words, the individual cells collude together and operate as a collective. The important thing to note here is that their circumstance, which in this case is availability of food, has a strong influence on how they behave.
