the act or result of diverging or the amount by which something diverges
2.
the condition of being divergent
3. meteorology
the outflowing of airstreams from a particular area, caused by expanding air
4. mathematics
a.
the scalar product of the operator, ∇, and a vector function, A, where ∇= i∂/∂x + j∂/∂y+ k∂/∂z, and i, j, and k are unit vectors. Usually written: div A, ∇A, or ∇A.
curl (sense 11), gradient (sense 4)
b.
the property of being divergent
5.
the spreading of a stream of electrons as a result of their mutual electrostatic repulsion
6.
the turning of the eyes outwards in order to fixate an object farther away than that previously being fixated
Compare convergence (sense 7)
7. Also called: divergent evolution
the evolutionary development of structures or organisms that differ from each other in form and function but have evolved from the same basic structure or organism
Compare convergence (sense 5)
Also called (for senses 1, 2): divergency, divergement

Recent studies have shown that under contrasting ecological pressures, patterns of modularity could be related to divergent evolution.

Thus, a massive annexin gene loss in several bacterial lineages or very divergent evolution would appear a likely explanation.
