This text critically examines the claim that natural evolution does not lead to interspecies harmony. The author argues to the contrary, suggesting that various forms of coexistence in nature prove that evolution frequently results in deep symbiotic relationships. Such complex symbioses often emerge from initial differences or even conflicts. Lichens serve as a prominent example of inter-kingdom symbiosis, where the participating organisms have become so interdependent that they can no longer survive individually. The text also discusses hypotheses regarding the origin of eukaryotic cells through total symbiosis and highlights the existence of dual inheritance. Furthermore, the abstract addresses the problematic definition of "naturalness" in evolution. It questions whether being natural simply implies the absence of human intervention or if the evolutionary process itself inherently transcends conventional concepts of nature. Ultimately, the text suggests that evolution is characterized by a fundamental tendency toward integration and cooperation, challenging the idea that interspecies harmony is an anomaly rather than a central feature of biological development.
