New study reveals how placental mammals evolved long pregnancies and complex placentas using single-cell transcriptomics across six species.

Pregnancy that lasts long enough to support full fetal development is a hallmark evolutionary breakthrough of placental mammals – a group that includes humans. At the center of this is the fetal ...
