Insectivora is a taxonomic grouping that was used to describe insect-eating mammals like armadillos, hedgehogs, moles, and anteaters. The taxonomy of these animals has beea revised in recent years, and Insectivora is no longer widely accepted because this group of organisms lacks one common ancestor and is instead descended from several ancestors. Which term best describes Insectivora? A. Polyphyletic B. Monophyletic C. Haplophyletic D. Paraphyletic
