Being one of Freud’s most famous contributions to psychoanalysis, the Oedipus complex is still a topic of heated interest. It has been disputed in many different disciplines ranging from anthropology to biology. This theoretical paper aimed to explain the phenomena that are represented by children’s affectionate and assertive attitudes towards their parents, named as the Oedipus complex by some, in terms of parent–offspring conflict, sibling competition, and infanticide. All of these evolutionary biological concepts or their combination could conceive specific relational settings similar to those emerging in the Oedipus complex. Psychoanalysis surely acknowledges the effects of parent–offspring conflict or sibling dynamics on familial relations and character formation. Nevertheless, they have been generally overshadowed by other primary theoretical concepts. Considering the findings from evolutionary biology and developmental psychology, it was asserted that parent–offspring conflict and sibling dynamics must be included in the conceptualization of oedipal-like behaviors. In light of these hypotheses, related literature and suggestions for further studies were discussed.

作为弗洛伊德对精神分析最着名的贡献之一，俄狄浦斯情结仍然是一个备受关注的话题。从人类学到生物学，它在许多不同的学科中都存在争议。这篇理论论文旨在从亲子冲突、兄弟姐妹竞争和杀婴方面解释儿童对父母的深情和自信的态度所代表的现象，被一些人称为俄狄浦斯情结。所有这些进化生物学概念或它们的组合都可以构想出类似于俄狄浦斯情结中出现的特定关系设置。精神分析肯定承认亲子冲突或兄弟姐妹动态对家庭关系和性格形成的影响。尽管如此，它们通常被其他主要的理论概念所掩盖。考虑到进化生物学和发展心理学的研究结果，有人断言亲子冲突和兄弟姐妹动态必须包括在类似俄狄浦斯行为的概念化中。根据这些假设，讨论了相关文献和进一步研究的建议。
