Document Summary
Increases in complexity over their life time and evolutionary time. Animals are open systems and are not isolated. The universe is increasing entropy because it is an isolated system. Animals are highly ordered systems: there are three basic statements that animals are highly ordered systems. This is a picture with several levels of structural organizations of animals. These animals are composed of several organ systems, which are composed of several organs and those organs are composed of several tissues which themselves are composed of cells which are composed of molecules and atoms and so forth. These organisms sort of assemble themselves to form populations and ecosystems. But animals don"t start off their lives as highly ordered systems. Most animals start off as a single cell which is much simpler compared to their highly ordered adult counterpart. They undergo this progressive increase in complexity over their lifetime. Therefore there is this evolutionary trend by increasing the complexity of the animal.
