A Momentary Flow

Evolving Worldviews

The idea that animal evolution is shaped by males boasting and fighting to win female favor is a central biological dogma. Females pick males whose exaggerated traits suggest virility, thus producing peacock feathers and sage grouse struts. Males compete for female favor, hence a stag’s antlers and fights for territorial domination. These are the main engines of sexual selection, the default explanation for differences between the sexes. Under closer scrutiny, however, the dogma doesn’t seem to hold. A new replication of English geneticist Angust Bateman’s foundational mid-20th century mate-choice study, a study that reinforced sexual selection assumptions and shaped decades of research, came to very different conclusions than the original. Bateman’s refutation may be an exclamation point for critics who say the evolutionary dance between sexes is far richer and more complicated than a male-dominated two-step.
