Evidence in the Study of Adaptive Evolution CANNOT Be Obtained

Question

Evidence in the study of adaptive evolution CANNOT be obtained from
A) comparisons of gene sequences within a genome.
B) comparisons of gene sequences between genomes.
C) the study of microorganisms growing in strongly selective environments.
D) sequencing a single genome several times (deep sequencing).
E) experimental evolution.

Accepted Answer

Deep sequencing may provide information on genetic variation within a single genome, but it does not necessarily provide evidence of adaptive evolution.
