The discovery empirically illustrates a fundamental requirement of organismal evolution – historical continuity of past and present functional associations.

For evolution to proceed, the maintenance of a currently adaptive configuration of traits must not preclude the incorporation of innovation in the same traits. In a new paper we propose a novel mechanistic principle that clarifies how local adaptation can be reconciled with continuity of evolution.
