On the other hand, not isolacionismo is a trend found in all the societies until today known. The news of contacts between the peoples are imemorveis. (Mello – 1987) Mello reaffirms that the cultural diffusion cannot have without has a contact, however the acceptance and the assimilation of the elements that the culture of the other composes are excellent the will of the individual, being able it to adopt or not them had cultural aspects in question. As Lowie exists the diffusion center, that serves to identify the points of origin of determined cultural trace, however the complexity occurs in demonstrating to the aiming of one definitive trace, which had to this the anthropologists searchs to demonstrate these phenomena of separate form: The Phenomenon of Parallelism and the Process of Aculturao. The Phenomenon of Parallelism mentions on inventions or inventos to it the related or parallel cultural groups, this process searchs to explain the origin of popular expressions, dictated and sayings, through research on the verbal traditions, however the complexity takes in them to a study directed toward history of one determined culture, the example the Brazilian culture –, that in its formation culture it received the influence from some cultural groups, Portuguese, French, Italian, African such as and this if prove in some sectors of the Brazilian culture, however they are in the popular expressions where the most diverse doubts regarding the point appear of origin, let us see some examples: – Children created, folded works (he also corresponds the Spaniard and Italians); – Nothing as one day after the other (he has correspondent in the Spaniard); – I discovered a saint for I covered another one (corresponding in the Frenchman); As we saw through the examples above cited the diffusion process demonstrates to some complexities in what disrespect the similarities between cultures, however this process obeys a dynamics that can be explained through a phenomenon that occurs inside of the process of cultural diffusion, in this in case that we mention the Process to it of Aculturao.
