Aphylogenetic tree or phylogeny:
a. must be rooted to properly convey evolutionary relationships.
b. shows how families of the same species are related
c. shows the exact dna change that led to the formation of a new species
d. is a hypothesis about individual relationships and depicts evolutionary history.
e. can illustrate selection pressures that have acted on species.

The correct answer is that a phylogenetic tree is a hypothesis about individual relationships and depicts the evolutionary history (D).

Explanation:

The phylogeny is not an actual representation of the relationship that exist between individual species, but an hypothesis formed to explain the evolutionary relationship between the species.

The phylogeny could be rooted or unrooted, rooted when the hypothesis can identify the common origin of the species represented, and unrooted hwen it is difficult to identify.
