Evolutionary trap
The term evolutionary trap has retained several definitions associated with different biological disciplines. == Evolutionary biology == Within evolutionary biology, this term has been used sporadically to refer to situations in which a pre-existing (and presumably well adapted and successful) trait has become obsolete or maladaptive (evolutionary mismatch) due to changing biophysical or social environments but evolved complex behavioral decision-making rules ("Darwinian algorithms") accumulated by prior adaptations now preclude any effective re-adaptation — as organisms can only modify upon or "patch up" existing traits (which essentially have become inherited "baggage") rather than devolving, removing or "redesigning" a trait (i.e.
