A scientist is trying to determine the evolutionary relationships among species with very similar physical characteristics. One method to determine the relationships is by comparing amino acid sequences of proteins.
Why would the scientist compare the amino acid sequences of proteins common to those similar species?
A Amino acid sequence differences provide evidence of gene flow among the species.
3 Amino acid sequence differences reflect the accumulated differences in the DNA of the spedes.
Amino acid sequence differences are the only useful data for constructing accurate dadograms of the species.
D
Amino acid sequence differences are the result of mutations caused by different selection pressures experienced by the
species.
