The evolutionary history determination of any branch of science, in my opinion, the fairest would be based on the assessment investigations made from ancient philosophers, who, still in the prehistoric period, were among the first scientists who initiated the general study of phenomena and events in the whole Universe. But from the beginning, through the science appeared the division of different disciplines from various scientific fields, which occurred also in Biology, thus appearing different fields, including Medicine, whereby it included the Parasitology discipline which still also is divided into different chapters (special problems), which broadly have not favored the general theoretical synthesis of Parasitology, which is practically absent in the current bibliography. Proceeding within the given situation, throughout my personal(original) and multiannual research I have summarized methodological oriented theoretical study with the aim of highlighting regularities that "directs" parasitical processes. So, I managed to develop " The Parasitic Processes Theory", and were established the seventh "activity" of regularities displayed sets in the "Scheme of parasitic process with spectrum components regularities and their interdependence " within the presented article.
