The secret to the origin of complex life lies within each of us.
Our cells are chimaeras,
formed through the amalgamation of two distinct types of simple cells,
one inside the other.
The mitochondria inside us were once free-living bacteria.
The same is true of the light-gathering chloroplasts of plant cells.
The complex cells of which all animals and plants are made
are the product of symbiotic mergers that occurred deep in the history of life.
Once the subject of great controversy, modern molecular techniques are uncovering evidence for
the critical role of symbiosis in the biological and ecological transformation of our planet.
In this exciting account, John Archibald explains this revolutionary
new view of life and its history that molecular biology is bringing to light.
