Answer:
The correct answer is : prokaryotic organisms like E. coli and higher organisms share common ancestor.
Explanation:
E. Coli is a prokaryotic organism or bacteria. On the metabolic level these organisms share similar homology with the higher organism other than this these organisms also show same core functions with higher level organisms such as elephant.
These similarities suggest that the all the living organisms share a common ancestor. The french scientist Jacques Monod statement "Anything found to be true of E. Coli must also be true of elephants." is also based on this notion.
