Abstract

The placenta is one of the most morphologically variable mammalian organs. Four major characteristics are typically discussed when comparing the placentas of different eutherian species: placental shape, maternal–fetal interdigitation, intimacy of the maternal–fetal interface and the pattern of maternal–fetal blood flow. Here, we describe the evolution of three of these features as well as other key aspects of eutherian placentation. In addition to interspecific anatomical variation, there is also variation in placental anatomy and function within a single species. Much of this intraspecific variation occurs in response to different environmental conditions such as altitude and poor maternal nutrition. Examinations of variation in the placenta from both intra- and interspecies perspectives elucidate different aspects of placental function and dysfunction at the maternal–fetal interface. Comparisons within species identify candidate mechanisms that are activated in response to environmental stressors ultimately contributing to the aetiology of obstetric syndromes such as pre-eclampsia. Comparisons above the species level identify the evolutionary lineages on which the potential for the development of obstetric syndromes emerged.

  • Epitheliochorial placentation avoids many of the immunological and hemodynamic problems associated with invasive forms of placentation that underlie complications of human pregnancy such as pre-eclampsia.

    “Epitheliochorial placentation avoids many of the immunological and hemodynamic problems associated with the invasive forms that underlie complications of human pregnancy, such as pre-eclampsia, and these may have operated as selective pressures over the millennia (131, 170, 231).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
