Various local structural probes detected subtle unusual changes in the local atomic structure and lattice dynamics of high temperature superconducting oxides at low temperatures. We propose that a part of these lattice anomalies and lattice anharmonicity is due to an unconventional electron-lattice interaction originating from the many-electron effect, and discuss its relevance to superconductivity.
