What it is
Living things are systems: genes code for proteins, proteins build cells, cells form bodies, and bodies live in ecosystems of predators, prey, plants and microbes. At every level, balance comes from feedback loops rather than from commands.
Biology’s tools have changed fast. The human genome was sequenced by 2003, and in 2021 AlphaFold showed that machine learning can predict a protein’s 3D shape from its sequence, work recognised by the 2024 Nobel Prize in Chemistry.

Ideas to carry
- 1
Emergence
Flocks, forests and brains do things no single part was told to do.
- 2
Feedback loops
Predators and prey, hormones and organs: balance comes from loops, not commands.
- 3
Code and shape
DNA stores the code; the folded protein does the work.
Established What we know
- The 1962 Nobel Prize in Physiology or Medicine recognised the discovery of DNA’s molecular structure.[1]
- The Human Genome Project produced a sequence of the human genome by 2003.[2]
- The 2024 Nobel Prize in Chemistry recognised computational protein design and protein structure prediction, including AlphaFold.[3]
Interpretation The older lens · Hermeticism and ecology
Old philosophy called the body a microcosm of the cosmos; ecology finds the same feedback loops at every scale.
