Modern mammalian X chromosomes date to the evolution of SRY from SOX3 and initial X/Y differentiation (blue/red), in the shared marsupial/placental ancestor. Subsequently, SDX arose by a retroposition of the autosomal gene MUM1 onto the X chromosome. Additional events included acquisition of additional sequence from an autosome (dark gray) and ongoing X/Y differentiation and Y degradation. Times from timetree.org.
