After Schrodinger (1944), are there other quantum physicists talking about life origin and evolutiion ? (ChatGPT 2023-8-21)

Yes, after Erwin Schrödinger's work in 1944, several other quantum physicists and scientists have explored the connection between quantum mechanics and aspects of life's origin and evolution. While these ideas have generated interesting discussions, it's important to note that the field of quantum biology, which explores the potential role of quantum phenomena in biological processes, is still a relatively new and evolving area of research. Here are a few notable figures and concepts in this field:

  1. Max Delbrück and Niels Bohr: Max Delbrück, a physicist and biologist, discussed the possibility of quantum effects playing a role in genetic mutations and biological evolution. He collaborated with Niels Bohr, one of the founders of quantum mechanics, on these ideas.

  2. Johnjoe McFadden: Johnjoe McFadden is a molecular geneticist who has proposed that quantum effects might be involved in processes such as enzyme catalysis, DNA mutations, and photosynthesis. He has written extensively on the subject and suggested that quantum coherence could play a role in maintaining the efficiency of biological systems.

  3. Stuart Hameroff and Roger Penrose: Although not quantum physicists in the traditional sense, these researchers have proposed a controversial theory known as "orchestrated objective reduction" (Orch-OR). This theory suggests that quantum processes in microtubules within neurons could be responsible for consciousness and might have relevance in understanding the nature of life and mind.

  4. Photosynthesis and Quantum Coherence: Some researchers have explored the idea that quantum coherence could enhance the efficiency of energy transfer in biological systems, particularly in the context of photosynthesis. Certain studies suggest that quantum effects might aid in the rapid and efficient transfer of energy in light-harvesting complexes.

  5. Quantum Effects in Enzymes: There is ongoing research into whether quantum tunneling and other quantum effects might play a role in enzymatic reactions, where reactions occur at rates that classical theories cannot fully explain.

It's important to emphasize that while these ideas are intriguing, the extent to which quantum effects play a significant role in the macroscopic and complex processes of life remains a subject of debate and investigation. Many biological processes can be adequately described by classical physics and chemistry, and the presence and relevance of quantum effects in these processes are still actively being explored and understood.
