of a lineage of organisms.

Adaptive radiations are typically marked by ecological and morphological as well as additional aspects of . See also as well as .

For divergence between lineages to occur to a substantial extent, then speciation is necessary as well. Thus, starting with a single , what one observes with adaptive radiation is an increase in the number (cladogenesis), an increase in the phenotypic diversity of these related species, and also an increase in the number of niches exploited by that lineage.

Examples of adaptive radiations can be seen in numerous lineages including those that gave rise to along with those that gave rise to ourselves or See also adaptive zone.
