Phylogeny in psychoanalysis is the study of the whole family or species of an organism in order to better understand the pre-history of it. [1] It might have an unconscious influence on a patient, according to Sigmund Freud. After the possibilities of ontogeny, which is the development of the whole organism viewed from the light of occurrences during the course of its life, [2] have been exhausted, phylogeny might shed more light on the pre-history of an organism.
The term phylogeny derives from the Greek terms phyle (φυλή) and phylon (φῦλον), denoting “tribe” and “race”; [3] and the term genetikos (γενετικός), denoting “relative to birth”, from genesis (γένεσις) “origin” and “birth”. [4] Phylogenetics ( /ˌfaɪloʊdʒɪˈnɛtɪks, -lə-/ [5] [6]) is the study of evolutionary relatedness among groups of organisms (e.g. species, populations), In biology this is discovered through molecular sequencing data and morphological data matrices ( phylogenetics), while in psychoanalysis this is discovered by analysis of the memories of a patient and the relatives.
