Camel Gain of pulley- shaped astragalus Poccary Pig -Hippo Whale Loss of pulley Deer Cow(10m)
Answer the questions about the phylogenetic tree below, which shows
our current understanding of the evolutionary relationships among
artiodactyls.

a. Name the outgroup. b. Name the sister taxon to the hippo. c.
Artiodactyls were once defined by the presence of a pulley-shaped
anklebone, the astragalus. Would a group of artiodactyls with a
pulley-shaped astragalus be a monophyletic taxon (clade), a
polyphyletic group, or a paraphyletic group? Explain your answer.
d. Is the camel ancestral to the other artiodactyls? Explain your
answer. e. Redraw the phylogenetic tree above to place the whale at
the top, without altering the phylogenetic relationships shown in
the tree.
