 For Mead, as noted, systems are not static. This is especially evident in the biological world. New forms of life arise, and some of them are due to the efforts of human beings, for example, the botanists who create hybrids. Mead argues that if a new form of life emerges from another form, then there is a time when the new organism has not fully developed, and therefore has not yet modified its environmental niche. In this situation the older order, the old environment, has not disappeared but neither has the new one been born. Mead refers to this state of betwixt and between as sociality.
