Which observation would provide the strongest evidence that most noncoding DNA is slightly deleterious?
A) Species with larger population sizes have more noncoding DNA.
B) Species with smaller population sizes have more noncoding DNA.
C) Species with larger genomes lose DNA more slowly through mutational processes than those with smaller genomes.
D) Species with larger genomes lose DNA more quickly through mutational processes than those with smaller genomes.
E) There is an inverse relationship between the total amount of DNA in the genome and the percentage of the DNA that is noncoding.

Species with smaller population sizes having more noncoding DNA suggests that noncoding DNA is slightly deleterious, as smaller populations are less efficient at purging deleterious mutations.
