Abstract

In this short article I discuss the relevance of two aspects of vesicle reactivity that are germane to understand the role of compartments in the origin of early cells. Studies of vesicle self-reproduction indicate that simple vesicles can grow and divide, maintaining inside most of their content and giving rise to a simple autopoietic system. New aspects of vesicle reactivity are also introduced, such as selection and competition processes within vesicle populations, emphasizing the concepts of vesicle diversity, inter-vesicles and vesicles-environment interactions, intended as synthetic analogs of primitive 'ecological' processes.
