Despite their phylogenetic distance from primates, the basic viscera layout—position of the liver, stomach, small intestine, kidneys, and reproductive organs—follows the general mammalian bauplan, allowing direct comparison to human anatomy textbooks.” Conclude by stating that the following report will
