How a radical new view of life could reveal its origin – and aliens
We've been looking at nature the wrong way, argues Rowan Hooper. If we stop focusing on the individual, we get a whole new picture of how life on Earth – and elsewhere – may have begun

The radical reimagining of life’s fundamental structure—shifting focus from isolated organisms to interconnected systems—could upend decades of biological orthodoxy. If proven, this framework might not only rewrite textbooks but also recalibrate our search for extraterrestrial life, making alien detection less about finding "little green men" and more about identifying the signature patterns of collective, self-organizing systems.
Background Context
The dominant model of biology has long treated individual organisms as the primary units of life, a perspective rooted in Darwinian evolution and molecular biology. Yet emerging theories in complexity science and systems biology suggest that life may instead emerge from dynamic networks of interaction, where the whole could be greater than the sum of its parts—an idea that predates modern science but has struggled to gain mainstream traction.
What Happens Next
Researchers will likely prioritize experimental validation of this framework, particularly in exploring how such networked systems could have spontaneously arisen from prebiotic chemistry. Meanwhile, astrobiologists may begin incorporating these principles into their instruments, scanning for alien biospheres not by looking for familiar organisms but by detecting the telltale signatures of systemic organization in distant exoplanets.
Bigger Picture
This shift mirrors broader scientific movements toward holism, from climate science’s emphasis on planetary systems to the rise of network theory in physics and ecology. As technology enables finer-grained observation of life’s intricate webs, the boundaries between disciplines are blurring—suggesting that the next major breakthroughs in biology may come not from deeper dives into genes or cells, but from mapping the invisible threads that connect them all.
