Digging burrows

Explanation:

A structural adaptation is an adaptation to the body structure of an organism. It mostly involves the physical characteristics of an organism. In this case, sharp teeth and long necks are descriptions of a possible structural adaptation while digging burrows may have been a behavioural adaptation as it is an action but not a physical trait of an organism so it is not an example of structural adaptation.

"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."
