Georges Cuvier, baptized Georges Jean-Leopold Nicolas-Frederic Cuvier, was a professor of anatomy at the National Museum of Natural History in Paris, France, through the late eighteenth and early nineteenth centuries. Scholars recognize Cuvier as a founder of modern comparative anatomy, and as an important contributor to vertebrate paleontology and geology. Cuvier studied the form and function of animal anatomy, writing four volumes on quadruped fossils and co-writing eleven volumes on the natural history of fish with Achille Valenciennes. Moreover, Cuvier constructed a system of classification based on specific and well-articulated principles to help anatomists classify animal taxa. Cuvier had public debate in 1830 with Etienne Geoffroy Saint-Hilaire, a dispute centered on whether form or function matters most for the study of anatomy and whether the transmutation of organic forms can occur over time. Cuvier's opinions influenced the development of biology in France, and his arguments against transmutation of types influenced the reception of Charles Darwin's theory of evolution by natural selection among many French naturalists.
Maria Regina Torloni and colleagues published “Classifications for Cesarean Section: A Systematic Review,” hereafter “Classifications for C-sections,” in 2011 in the journal PLOS One. A Cesarean section, or C-section, is a surgical birth through an incision in the pregnant person’s abdomen and uterus. Across the world, medical professionals use many different C-section classification systems to group the procedures according to particular features of the medical situation, such as the person undergoing the C-section or their specific medical needs. The authors of “Classifications for C-sections” systematically review the various available classification systems and evaluate them to identify their strengths and weaknesses. In “Classifications for C-sections,” the authors stress the need for a standardized classification system that experts can use to communicate internationally and address the health needs of pregnant people seeking C-sections.
