Question

Which of the following pieces of evidence most strongly supports the idea that all life on earth evolved from a single common ancestor?

• A. All life requires a constant input of energy from its environment.
• B. All organisms use the same molecules (DNA and RNA) to store and transmit hereditary information.
• C. All organisms reproduce.
• D. All organisms experience evolution at the individual level.

Answer 1

The correct option is B All organisms use the same molecules (DNA and RNA) to store and transmit hereditary information.

Right from unicellular bacteria to human, the genetic material is DNA, the formation of proteins require RNA, this indicates a common origin

So, the correct answer is 'All organisms use the same molecules (DNA and RNA) to store and transmit hereditary'
