#Question id: 9621
#Unit 9. Diversity of Life Forms
If this evolutionary tree is an accurate
depiction of relatedness, then which of the following should be correct?
1. The entire tree is based on maximum
parsimony.
2. If all species depicted here make up a
taxon, this taxon is monophyletic.
3. The last common ancestor of species B
and C occurred more recently than the last common ancestor of species D and E.
4. Species A is the direct ancestor of both
species B and species C.
5. The species present at position 3 is ancestral to C, D, and E
