In other words, it is when one species 'explodes' into a variety of closely related species, each of which evolves different modifications to allow it to specialize in some or other aspects of its lifestyle. Four features can be used to identify an adaptive radiation:

Note that this is not the same as a monophyly in which all descendants of a common ancestor are included.- A phenotype-environment correlation: a significant association between environments and the morphological and physiological traits used to exploit those environments.- Trait utility: the performance or fitness advantages of trait values in their corresponding environments.- Rapid speciation: presence of one or more bursts in the emergence of new species around the time that ecological and phenotypic divergence is underway....
