How can dna be useful in phylogeny?
a. dna isn't useful in phylogeny, as morphological characteristics are used exclusively in phylogeny.
b. dna sequences from different species can be compared, giving us more information about their evolutionary relationships.
c. dna sequences are rearranged to predict how species could evolve in the future.
d. dna from every organism in a clade is sequenced to identify genetic mutations that have occurred
