Does a fish need a bicycle? Animals and evolution in the age of biotechnology.

Animals, in the age of biotechnology, are the subjects of a myriad of scientific procedures, interventions, and modifications. They are created, altered, and experimented upon--often with highly beneficial outcomes for humans in terms of knowledge gained and applied, yet not without concern also for the effects upon the experimental subjects themselves: consideration of the use of animals in research remains an intensely debated topic. Concerns for animal welfare in scientific research have, however, been primarily directed at harm to and suffering of animal subjects and their prevention. Little attention has been paid to the benefits research might potentially produce for animals themselves and the interests that some animals may therefore have in the furtherance of particular avenues of science.
