Question

a scientist is trying to determine the relationship between clams, snails, and squid. when she generates a molecular clock, she is surprised to see that clams and squid are more closely related than clams and snails. which did the molecular clock data show? clams and snails are more similar in related structures than clams and squids. clams and snails have more in common genetically than clams and squid. clams and squid have been evolving separately for a shorter time than clams and snails. clams and squid have been evolving separately for a longer time than clams and snails.

Explanation:

A molecular clock uses the rate of molecular changes (such as in DNA) to estimate the time of divergence between species. If clams and squid are more closely related than clams and snails, it means they have been evolving separately for a shorter time.

Answer:

Clams and squid have been evolving separately for a shorter time than clams and snails.
