Certain apparently advantageous traits have failed to evolve due to evolutionary constraints
Multiple studies demonstrate that evolutionary, genetic, and phylogenetic constraints frequently limit or prevent the adaptation of populations and species to changing environmental pressures.
The claim states that certain apparently advantageous traits have failed to evolve due to evolutionary constraints. The retrieved papers provide multiple robust lines of evidence—ranging from theoretical population genetics to empirical findings in birds, plants, and marine organisms—showing that genetic, phylogenetic, and physiological constraints actively limit adaptive evolution. Thus, the claim is well-supported by the literature.

The authors demonstrate that certain passerine breeding traits are limited by strong phylogenetic inertia.
