地球生物化学的基本前提是，地球上出现了生命，在那里有催化作用的机会，以加速水-岩石-有机系统中化学能的释放。在这个框架中，生命是对这样一种困境的行星反应，即冷却会降低非生物过程的速度，以至于化学能被捕获。通过新陈代谢的催化作用释放了被困住的能量，而生命通过捕捉释放的部分能量而受益。出于需要，生化过程有地球化学起源，而地球生物化学断言，这些起源可以通过将反应机制映射到深部时间来揭示。我们提出了五项原则，这些原则应该有助于指导新兴的地球生物化学领域的研究。
The basic premise of geobiochemistry is that life emerged on Earth where there were opportunities for catalysis to expedite the release of chemical energy in water–rock–organic systems. In this framework, life is a planetary response to the dilemma that cooling decreases the rates of abiotic processes to the point that chemical energy becomes trapped. Catalysis via metabolism releases the trapped energy, and life benefits by capturing some of the energy released. Out of necessity, biochemical processes have geochemical origins, and geobiochemistry asserts that these origins can be revealed by mapping reaction mechanisms onto deep time. We propose five principles that should help guide research in the emerging field of geobiochemistry.
