If you compare the original DNA with the mutated DNA, the first C got “substituted” by an A after the mutation.
So the answer is (C) substitution.
The answer is <span>They both suggest that snakes evolved from an ancestor with legs.
The second choice is not correct since we have no information about pythons and other snakes. We only have the relationship between geckos, snakes and legless eels. So, it is said that </span><span>snakes in general have more DNA sequences in common with four-legged geckos than they do with legless eels. This means that snakes are closer to geckos than the legless eels. We cannot conclude from this information which evolved from which, but we can say that </span><span>snakes evolved from an ancestor with legs.
In different case, if the snakes had more DNA sequence in common with legless eels, we would conclude that the snakes evolved from an ancestor without legs.</span>
First, tell your teacher that the Sun is not at the center of the UNIVERSE. He observatory that occasionally planets would travel backwards in the night sky & people also observed the moons rotating around Jupiter to prove his theory.
