In the continuity of life, extinction is foiled by the radiation of new species; in the history of our biosphere, both diversity (the number of species) and biomass (their sheer substance) have burgeoned through time.
Academic text (1999) -
Their extinction made room for the subsequent radiation of mammals into newly vacant ecological niches.
Academic text (2003) -
What factors fostered the evolutionary radiation of species within the genus, and what factors permit the assembly and coexistence of multiple species?
Academic text (2005) -
Clades that have undergone recent and rapid radiations offer unique insights into the processes that drive diversification.
Academic text (2018) -
West Indian Anolis lizards also exemplify adaptive radiation, replicated four times and with much the same outcome on each island.
Academic text (2007) -
The rapid radiation of amphibians filling various ecological roles was a key event in the diversification of life during the Triassic period.
-
Darwin's studies of adaptive radiation in birds provided important evidence for the theory of evolution.

Etymology
Radiation comes from the Latin radius, meaning 'ray' or 'spoke', and gives the strong image of spreading out from a source. In biology, radiation describes groups that spread into new places and change into new forms, so the word paints evolution as a 'ray-like' spreading out.
