Fossil evidence suggests that whales evolved from land mammals. Using comparative DNA techniques, scientists have also suggested that whales are related to hippos. How could comparing amino acid sequences support the theory of evolution?
Question 6 options:
By comparing amino acid sequences, scientists were able to prove that ancient whales had the same DNA base pairs as ancient hippos.
Comparing amino acid sequences can show close genetic relationships between organisms that may appear very different, such as whales and hippos.
Comparing amino acid sequences showed that stabilizing selection took place in a population of hippos, resulting in the formation of a new species of whale.
By comparing amino acid sequences, scientists were able to prove that whales evolved from hippopotamus ancestors.
