this question should be corrected:
i think u r trying to say:
Which are the most challenging ANSWERS in biology that haven't yet been identified?
(because many challenging questions can be asked - but usually with no answer)
now answering the so-called 'corrected' question:
Which are the most challenging answers in biology that HAVE BEEN identified?!!!!!!!!!!!

Which one gives the order? The brain or the DNA? I think the brain is like a processor waiting for input from the eyes, ears, mouth, and other sensors, but the DNA has the final word.

Would that be "Did man evolve from ape? If so, why do we still have ape?" Just a guess, biology wasnt my best subject.
