Antonio Eusebio Lazcano Araujo Reyes is a Mexican biology researcher and professor of the School of Sciences at the National Autonomous University of Mexico in Mexico City. He has studied the origin and early evolution of life for more than 35 years.

Stanley Lloyd Miller was an American chemist who made important experiments concerning the origin of life by demonstrating that a wide range of vital organic compounds can be synthesized by fairly simple chemical processes from inorganic substances. In 1952 he performed the Miller–Urey experiment, which showed that complex organic molecules could be synthesised from inorganic precursors. The experiment was widely reported, and provided evidence for the idea that the chemical evolution of the early Earth had caused the natural synthesis of organic compounds from inanimate inorganic molecules.
