Fossils are significant in showing the evolution of species. Fossils can be used to determine features that are shared between the current living organisms and ancient organism which they are related. This can be used to study how organisms evolve and how this is related to the ecological conditions of the time compared to now. Organisms evolve so they can adapt to a changing habitat.
Answer:
The correct option is B
Explanation:
The <u>biomolecule used in comparing lizards A and B is the mitochondrial DNA while that used to compare the same lizard B to another lizard C is the ribosomal RNA (rRNA)</u>. <u>They should have compared the same biomolecules throughout</u> by extracting the mitochondrial DNA of the three lizards and then proceed to sequence the whole genome of the lizards. After which they can now do a Global alignment (comparison) of the three sequences together. This procedure would have given them a more accurate information on there identity and similarity.
