In vector calculus, divergence is a vector operator that measures the magnitude of a vector field's source or sink at a given point, in terms of a signed scalar. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point. For example, consider air as it is heated or cooled. The relevant vector field for this example is the velocity of the moving air at a point.
(Redirected from Divergent Evolution). Definition. noun. (1) The process by which an interbreeding population or species diverges into two or more descendant species, resulting in once similar or related species to become more and more dissimilar. (2) The process of tracing back two or more species to their common ancestor that indicate how they have diversified and diverged. Supplement. For example, a flock of bird in migration gets divided as half of them settled to a new island while the other half continued migrating to a farther land.
