Species recognized by the phylogenetic species concept
a. sometimes also would be recognized as species by the biological species concept.
b. are sometimes paraphyletic.
c. are characterized by symplesiomorphies.
d. are more frequent in plants than in animals.
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
In the figure below, Taxa I, II and III are as follows:
A.
paraphyletic, polyphyletic, monophyletic
B.
paraphyletic, monophyletic, polyphyletic
C.
polyphyletic, monophyletic, paraphyletic
D.
monophyletic, polyphyletic, paraphyletic
