Why can DNA be used to determine phylogeny OA DNA sequences

Why can DNA be used to determine phylogeny OA DNA sequences change as species evolve so comparing sequences from different species helps determine how closely related they are B Organisms with common ancestors have identical DNA sequences OC DNA sequences become more efficient over time so modern organisms have less DNA compared with their ancestors D Organisms gain more genes as they evolve so the larger the genome the more time that has passed since the species emerged
