C) There are six living species of mammals called hyraxes in the order

Hyracoidea. These are small rabbit-like mammals that are also considered

to be close relatives of both dugongs and elephants. All of these mammals

are widely different morphologically. Explain how organisms that are widely

different in morphology can have a close evolutionary relationship.

Animals in the same order are similar evolutionarily, but are still very different species.

Explanation:

Animals in the same order have a common evolutionary ancestor that may give them similar traits, but the species can still be very different with morphologies.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.
