Perhaps at no time in human history has biological research progressed
so rapidly or held so much promise. With the understanding we now have
of the molecular underpinnings of life, we can ask--and answer--important
new questions. Yet, as much as we know about life processes, there is
so much more we do not know. Biological research does, indeed, hold
great promise. Scientific observation of animals is likely to lead to treatments for
an array of human and animal ailments as well as strategies to improve the
production and quality of food and fiber and many other advances.
But that promise never will be realized unless we continue to question, to experiment.
