摘 要：The expression of cancer is similar to processes that in unicellular organisms grant convenient properties, such as immortality. The presence of oncogenes and proteins in viruses, protozoa and invertebrates is recognized. The study of these characters, at each biological level, represents the way to establish phylogenetic relationships. In unicellular and colonial organisms these characters provide the courage to face a threat. In humans they are inactive and return to express themselves only if there is potential chronic damage. Then they modulate other genes that will respond to the cellular aggressor, leading to unicellular immortality (cancer). It is relevant to evaluate the final or teleological origin of the cancer, which is not currently known. This review provides a theory that would explain why a normal cell becomes neoplastic. Molecular Phylogeny is the final teleological mechanism, whereby transformed cells recapitulate the expression of genes and their products, through molecular maneuvers that assist in responding to adverse factors, referred to as epidemiological levels as risk factors. Self-replication remains the first objective of life on earth. The teleological cause of cancer encompasses this phylogenetic mechanism of damage response. Therefore, I conclude that the final origin of cancer may be a biological adaptation mechanism, called molecular phylogeny. If this theory is verified, it could fill the gap that currently persists on the teleological origin of cancer.
