Which hypothesis do the similarities in the bone arrangements support? a. These organisms are members of the same species.

b. These organisms may have descended from the same ancestor.

c. These organisms have adaptations to survive in different environments.

d. These organisms all contain the same genetic information.

B

Explanation:

A similarity in the arrangement of bones in organisms can be hypothesized to be an indication of the organisms descending from the same ancestor.

The similarity in the arrangement of bone in different organisms is one of the morphological evidence used to support the theory of organic evolution which says that all living organisms are of the same descent with modification from common ancestors.

The similarity in the arrangement of bones falls under homology. Homologous organs are similar in structures but different in functions. For example, the pentadactyl limbs of vertebrates. Mammals, birds, reptiles, and amphibians all have limbs that are built on a five-digit plan but the functions of the limb vary within and among different groups of vertebrates.

"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."

this is a good question! i'll do some research and come back when i have the answer!
