( Carbon chauvinism)
Carbon chauvinism is a relatively new term meant to disparage the assumption that extraterrestrial life will resemble life on Earth. In particular, it would be applied to those who assume that the molecules responsible for the chemical processes of life must be constructed primarily from carbon.[1] It suggests that, as carbon-based life forms who have never encountered any life that has evolved outside the earth’s environment, human beings may find it difficult to envision radically different biochemistries. The term was used as early as 1973, when Carl Sagan described it and other human chauvinisms that limit imagination of possible extraterrestrial life in his Cosmic Connection.[2] In a 1999 Reason magazine article discussing the theory of a fine-tuned universe, Kenneth Silber quotes astrophysicist Victor J. Stenger using the term[3] name="References" id="References">
