IMPORTANT POINTS & DISCOVERIES

  • The hemochorial placenta evolved early during mammalian evolution. This finding challenges the prevailing view that the hemochorial placentation is a ‘derived’, rather than an ancient form
  • Galectins are key molecules that might participate in tolerance, especially during primate pregnancies
  • The gene encoding the progesterone receptor has undergone adaptive changes during recent human evolution
  • Unraveling of the relationships among placental mammals using phylogenomic methods
  • Natural selection pressures are different in genes highly expressed in the prenatal when compared to those in the postnatal environments
