Abstract
In this paper, I adopt the view that the form which is embodied in matter gives it its essence and converts it into substance (Aristotle). I furthermore understand information as the transmissible state of the form. Living beings as substances can create order in their environment adapted to their needs. The environment in turn has the potential to change the form and other causes such as matter, efficiency/functionality, and goal/intention. Living beings can internalize these changes, propagate them through replication, or share them as information with others. Living beings have progressively acquired through this process advanced form- and information-processing and generation abilities. This positive feedback loop with enhancement in form and information has become one of the main drivers of biological evolution. Based on these considerations, I will address the nature of form and information and the changes that they have undergone during biological evolution.
