"(...) the power for growth comes from the reactivity of the environment, wich fluxes continuously through living cells (in the form of food and oxygen in our case, photons of light in the case of plants). Living cells couple this continuous energy flux to growth, (...) through ingenious structures, in part specified by genes. But whatever those structures may be (...), they are themselves the outcome of growth and replication, natural selection and evolution, none of which is possible in the absence of a continuous energy flux from somewhere in the environment."
