In this article, I will start showing how radical genetic enhancements may accelerate the conversion into a novel species. I will also clarify the concepts of ‘biological species’, ‘transhuman’ and ‘posthuman’. Then, I will summarize some ethical arguments for creating a transhuman or posthuman species with a substantially higher level of well‐being than the human one. In particular, I will present what I shall call the Principle of the Best Interests of Posthumanity, which states that the enhancement of the human and transhuman species must be directed towards the creation of a posthuman existence that is substantially more valuable than its predecessors. I suggestthathuman extinction maybe considered, within that principle, as one of the best interests of posthumanity. Finally, I will develop three objections that make that principle unattractive and that show that pursuing a full‐blown programme of posthuman evolution is ethically flawed.}, organization = {This research is funded by an INPhINIT Retaining Fellowship of the La Caixa Foundation (Grant number LCF/BQ/DR20/11790005).
