Heterotrophic Theory
idea that early cells developed in an atmosphere with NO FREE OXYGEN
CO2, H2, NH3, H2O (sulfur?)
1953 Miller & Urey
CH4 NH3 H2 H20
continuous source of energy (heat)
electric spark
after 1 week 10-15% carbon is organic and 2% is in amino acid
Criticism
constant energy source doesn't effectively mimic earth
