What specific type of placenta do woolly monkeys possess, which supports traits common to higher primates?

Answer

A zonary, labyrinthine placenta

Woolly monkeys share a specific physiological marker with many other primates, indicated by the structure of their placenta. This structure is classified as zonary and labyrinthine. This specialized arrangement is crucial because it facilitates an extensive surface area for the necessary exchange of nutrients and the removal of waste products between the mother and the developing fetus. This efficient exchange system is what allows for the biological investment required for primates that exhibit relatively large brain sizes and consequently undergo longer gestation periods, hallmarks of higher primate development that distinguish them from many other mammalian orders.
