Denis Noble, a renowned systems biologist known for his pioneering work on heart electrical activity, teams up with Michael Levin, a leading expert in bioelectricity. They challenge traditional views, arguing that DNA is not the sole blueprint of life and critique the reductionist approach of Neo-Darwinism. Their discussion dives into epigenetic inheritance and the need for a holistic understanding of biology. They advocate for integrating functional networks to better tackle diseases, pushing for greater funding and focus on complex biological interactions.

ANECDOTE

From Reductionism to Systems Biology

  • Denis Noble started in a reductionist camp studying ion channels but later realized cell membrane voltage represents a global, higher-level property.
  • This led him to view causation in biology as top-down, integrating both molecular and system-wide perspectives.
ADVICE

Combine Reductionism and Systems View

  • Combine reductionist and systems approaches by studying molecular components within global cellular constraints.
  • Understanding complex phenomena like cardiac arrhythmias requires analysis beyond single cells, at tissue and organ levels.
INSIGHT

Neo-Darwinism's flawed DNA replication

  • Neo-Darwinism falsely assumes DNA self-replicates like a crystal; in reality, living cells orchestrate error correction.
  • DNA alone cannot recreate an organism; life requires whole cellular context for replication and function.
