concrescence
/kənˈkrɛs(ə)ns
/noun [mass noun] Biology
The coalescence or growing together of parts originally separate.However, the two theories do clash, and this stems from the implicit assumption in the lepidomorial theory that ontogenetic and phylogenetic patterns equate; i.e., phylogenetic concrescence results from ontogenetic concrescence....
- Indeed, on this basis it is possible to reject the implicit axiom of the lepidomorial theory, that all change occurs through ontogenetic concrescence, as well as the principle that ontogenetic concrescence is possible.
- Phylogenetic patterns of concrescence and differentiation are similarly achieved through ontogenetic developmental differentiation, or a lack thereof.

Origin
Early 17th century (in the senses 'growth by assimilation' and 'a concretion'): from con- 'together' + -crescence, on the pattern of words such as excrescence. The current sense dates from the late 19th century.
