"It Was Lowenstam'S 1961 Discovery Of Biochemically-Precipitated Magnetite (Fe3o4) As A Capping Material In The Radula (Tongue Plate) Teeth Of Chitons (Marine Mollusks) That Was To Shape The Future Of Biomineralization. Prior To This Discovery, Magnetite Was Thought To Form Only In Igneous Or Metamorphic Rocks Under High Temperatures And Pressures. In His 1962 Paper Heinz Noted The Implications Of His Discovery With His Observation That The Chitons Were Known For Their Local Homing Instinct, Implying That They May Be Using A Magnetite Compass To Aid In Navigation. Subsequent Researchers Building Upon This Work Have Confirmed The Central Role Of Magnetite As The Biophysical Transducer Of The Magnetic Field In Living Organisms Spanning The Evolutionary Spectrum From The Magnetotactic Bacteria To Mammals, With A Fossil Record Extending Back At Least 2 Billion Years On Earth And Perhaps 4 Billion Years On Mars. Lowenstam Left Implications Of Biomagnetism For Others To Explore And Continued To Pursue Answers To How Organisms Control Mineral Formation. Over The Next Two Decades He Continued To Discover And Catalog Biologically Precipitated Minerals And Document Their Phyletic Distribution, As Well As Attempt To Track Their Evolutionary Origin. Heinz A. Lowenstam Was Elected To The National Academy Of Sciences In 1980. Artikel-Nr. 020506
