The simple insight that most changes are random had a profound effect on genetics, evolution and ecology.
In three bursts of adaptive change, one species of cichlid fish in Lake Tanganyika gave rise to hundreds.
Even genes essential for life can be caught in an evolutionary arms race that forces them to change or be replaced.
The physicist Jeff Gore tests theories about microbe communities experimentally and finds new rules governing ecological stability.
Carpenter ants need endosymbiotic bacteria to guide the early development of their embryos. New work has reconstructed how this deep partnership evolved.
Recent major surveys show that reductions in genomic complexity — including the loss of key genes — have successfully shaped the evolution of life throughout history.
