A 3D view of the structure of hemoglobin. |
“The knowhow, so to speak, to make salt is already in the sodium and chlorine:Na + Cl → NaCl
but the knowhow to make hemoglobin molecules and lemurs is not secretly coded in the carbon, hydrogen, and nitrogen:2932C + 4724H + 828N + 840O + 8S + 4Fe → C2932H4724N828O840S8Fe4
Life is a countercurrent to entropy, an energetic fight uphill in a world that typically moves thermodynamically downhill (despite some negentropic eddies, and despite some irreversible thermodynamics). Thermodynamics need be nowhere violated, because there is a steady ‘downhill’ flow of energy, as energy is irradiated into earth from the sun, and, eventually, reradiated into space.”
