Сould life begin in oil?

Paul Bracher, Ph.D., assistant professor in the department of chemistry at Saint Louis University, and his research team have been awarded a three-year $597,380 grant from the National Science Foundation (NSF) to study what life might look like on other planets – or, here on earth – if it began in oil.


The SLU team is one of four groups of chemists and biologists across the country involved in the project. Their ideas were generated at an “Ideas Lab” co-sponsored by the NSF and NASA. In a week-long workshop, scientists from a variety of backgrounds and skillsets were sequestered in a remote city in Maryland and charged with developing out-of-the-box ideas about the origin of life.

“In terms of the history of the planet, I think that how life originated has got to be the greatest scientific question we can ask,” Bracher said. “To move from mixtures of chemicals to a living system capable of self-replication and evolution – nothing more interesting has happened than this.”

While life as we know it on Earth relies on in aqueous environments where water is a solvent, some celestial bodies are covered not with liquid water but with liquid oils. Titan, a moon of the planet Saturn, has lakes of organic hydrocarbons and methane rain.

Were life to develop on oily worlds, the biochemistry of these organisms would have to be different. What molecules could be responsible for storing genetic information? What chemistry could decode genes and synthesize catalysts for biological functions? Those are some of the questions for which the project hopes to provide answers and clues.

“We want to establish the rules of how life might develop and evolve in oil,” Bracher said. “A lot of the chemistry that works in water doesn’t work in organic solvents.”

“The premise of our project focuses on places like Titan and exoplanets – planets around distant stars….
