Apaleontologist is trying to be study the dna of a fossil from an extinct animal called x. he has formulated three hypotheses. which hypothesis cannot be tested?

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
