By studying the basic biochemistry shared by many organisms, we can begin to piece together how biochemical systems evolved near the root of the tree of life.

Biochemical evidence of evolution is based on the fact that certain enzymes and chemical processes are found in the cells of all or nearly all life on Earth.

Here we articulate the paradigm of evolutionary biochemistry, which aims to dissect the physical mechanisms and evolutionary processes by which biological molecules diversified and to reveal...
