Absolutely. I value human life more than animal life. That does not mean to say I am for ill treatment of animals or even unnecessary testing. Cosmetic testing may have gone too far. However, using animal subjects that could lead to curing major diseases in quite acceptable.
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals in experiments. It includes pure research such as genetics, developmental biology, behavioral studies, as well as applied research such as biomedical research, xenotransplantation, drug testing and toxicology tests, including cosmetics testing. Animals are also used for education, breeding, and defense research. More: en.wikipedia.org.
Having in mind that our goal, as a human species, is surviving. We make evrything to assure that we can live better for more time. If so we need to test drugs or whatever in animals, so be it. We must have in mind that only we should do that when we have some theorical background support, and not use one of the scientific methods, try and repeat
Of course, how else will we advance our biotechnology fast enough to save millions/billions of potential lives? We are not at the point yet of giving this up, that point would be a quasi perfect simulation. Biotechnology advances slow enough already (the slowest tech in my view) for us to give up our best tools.
So: Yes, on every species!
