you are studying two animal species. you hypothesize that they are very distantly related to each other. what would be most useful for testing your hypothesis?
comparing their skulls
analyzing their dna
comparing their embryos
none of the answers listed

Explanation:

To test if two animal species are distantly related, analyzing their DNA is most useful. DNA provides the most accurate and detailed information about genetic relationships. Comparing skulls (morphology) or embryos (developmental) can have similarities due to convergent evolution, but DNA directly reflects evolutionary relatedness at the genetic level.

Answer:

B. analyzing their DNA (assuming the option for "analyzing their DNA" is labeled as such; if the options were labeled with letters like A, B, C, D, and "analyzing their DNA" is, say, option B, then the answer would be B. analyzing their DNA)
