Rare Earth hypothesis - Wikipedia
Cases against the Rare Earth hypothesis take various forms. The hypothesis concludes, more or less, that complex life is rare because it can evolve only on the surface of an Earth-like planet or on a suitable satellite of a planet. Some biologists, such as Jack Cohen, believe this assumption too restrictive and unimaginative; they see it as a form of circular reasoning. Tectonic significance of Australian rare earth element,,01-08-2020· Abstract. Australia is host to a diverse range of rare earth element (REE) ore deposits, and therefore is well placed to be a major supplier of REE into the future.
