Apes are People too !

Would this proscribe any medical tests that involve primates?
I am interested to know if there are opponents to this proposition.
Seems there would be substantial human 'costs' involved on a number of levels.

I guess my gut instinct is to agree with them.
I am no tree-hugger and I put the interests of humans before other animals, but it is difficult to challenge their arguments on a biological level.
Evolution tells us there is really nothing special about humans (except our excessive reverence for our own species) and all evidence suggests these animals have high intelligence and are capable of a great deal of sensitivity, emotion, empathy, etc.Also, wouldn't that make harming a great ape punishable at the same level as harming a human? I see some major legal issues arising here.Again, I am curious about those who would oppose this proposition and what sort of reasoning they might use to justify their opposition (scientific, religious, political).

These are obviously very sentient creatures.
Most species are endangered or declining wherever they occur.
Its not like they are a threat to rise up and start a new political party.
They are our closest biological relatives on the planet.
If we can't make an overture of humanity towards them, what hope does the rest of 'creation' have?
