Our results suggest that the emergence of prenatal conflict during the evolution of the placenta correlates with a suite of phenotypic and behavioural male traits that is associated with a reduced reliance on pre-copulatory female mate choice. Illinois animal biology professor Christina Cheng led a study that traced the evolution of a gene for an antifreeze protein in an Antarctic fish from the gene for a protein with an entirely different function. For example, the team discovered the Tiktaalik's pelvic girdle was nearly identical in size to its shoulder girdle. Here we apply comparative methods to test a key prediction of this hypothesis, which is that the evolution of placentation is associated with reduced pre-copulatory female mate choice.

The new finding also supports the proposed mechanism, called "escape from adaptive conflict," by which this can occur.
