Why is decidualization important?

The second explanation suggests that spontaneous decidualization developed as a way to get rid of embryos with genetic abnormalities. The embryos of humans and other primates are more prone to genetic abnormalities. Once the uterine lining thickens, its cells can detect genetic problems and remove defective embryos, before the mother uses valuable resources on an embryo that will not develop into a healthy fetus. This is especially important in species, like humans and apes, that have long pregnancies and tend to only have one baby at a time.

Why do fetuses burrow into the uterus?

In all mammals, fetuses burrow into the uterine lining, seeking nourishment ; however, the fetuses of some species are more aggressive than others. In some animals, like livestock, fetuses sit on the surface of the uterine lining, doing very little burrowing. In primates and humans, fetuses are more aggressive, burrowing deeply into the lining to get as much nourishment as possible. Emera suggests that spontaneous decidualization evolved as a means to protect the mother’s body from these more aggressive and invasive fetuses.
