Ascientist 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?
a) clams and squid have been evolving separately for a longer time than clams and snails.
b) clams and squid have been evolving separately for a shorter time than clams and snails.
c) clams and snails have more in common genetically than clams and squid.
d) clams and snails are more similar in related structures than clams and squids.

D.clams and snail are more similar in related structure than clams and squids

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
