As the earliest known fossil ancestral to placental mammals, Juramaia providesd fossil evidence of the date when eutherian mammals diverged from other mammals: metatherians (whose descendants include marsupials such as kangaroos) and monotremes (such as the platypus).
In eutherian mammals, sex determination is dependent on the Y-gene Sry, but in the other major mammalian class, the metatherians, it is controlled not only by a Y-locus, but also by the complement of X chromosomes.
Eutherian mammals have an XY system where SRY on the Y determines maleness, so XXY is male and XO is female.
