Abstract Sex chromosomes are widespread in species with separate sexes. They have evolved many times independently and display a truly remarkable diversity. New sequencing technologies methodological developments allowed the field of molecular evolution to explore this diversity large number model nonmodel organisms, broadening our vision on mechanisms involved their evolution. Diverse studies us better capture common evolutionary routes that shape sex chromosomes; however, we still mostly fail explain why so diverse. We review over half century theoretical empirical work chromosome highlight pending questions origins, turnovers, rearrangements, degeneration, dosage compensation, gene content, rates also report recent progress understanding ultimate reasons for chromosomes’ existence.
