Christianity and Animal Rights, part 8: Human Anatomy
I have been arguing that animal rights is essential not only for animal
protectionism (as mandated by the Bible) but also for human rights and human
well-being. People have generally defended exploitation and abuse of animals
on the grounds that humans are superior to nonhuman beings. Indeed, it
appears that one reason that humans kill and eat animals is to demonstrate
this supposed superiority. (See Meat: A Natural Symbol by Nick Fiddes.) Are
humans actually meant to eat flesh, and, if not, what are the implications
of living in a way that does not accord with our nature?
Milton R. Mills, MD has reviewed the literature on the comparative
physiology of humans and animals. He has made a compelling case that our
bodies most closely resemble herbivores (who eat only plant foods) and not,
as most people believe, omnivores (who eat both plant foods and animals). Similarities
with herbivores, but differences from omnivores, include numerous aspects of
mouth and dental structures, saliva composition, stomach acidity, stomach
volume, length of intestines and colon, kidney urine concentration, and nail
structure. It is curious that people rarely eat raw flesh, and they do not
seem to have much of a taste for cooked flesh, either. People almost always
add flavoring to flesh, such as salt or more complex sauces or spices. In
contrast, many people enjoy vegetables without additives. [I acknowledge
David Cantor of
Responsibilities for All for this insight, and I have found my extensive
correspondence with him helpful.]
Though evidence indicates that humans are designed to eat plant foods,
herbivores can consume flesh, which is how mad cow disease spread. There is
evidence that early humans ate some flesh, and there is archeological
evidence of consumption of animal flesh among early humans. These findings
do not demonstrate that early humans consumed much flesh. When food sources
were scarce, particularly protein-rich sources, there were incentives to
pursue flesh. Hunting was one option, though it was difficult to kill
animals with crude stone-age weapons. Many anthropologists believe that
scavenging for carrion was likely the main source of animal flesh among
early humans. In Man the Hunted, Donna Hart and Robert W. Sussman have made
a compelling case that human tool-making and social organization were
largely spurred by the need to avoid becoming prey, not to prey on other
animals.
We are intelligent, socially sophisticated creatures whose skills at
developing and transmitting culture have made us much more powerful than any
other creatures on earth. Attributes that evidently developed primarily for
human defense against predators have become potent offensive weapons. Humans
have found it convenient and adaptive to dominate animals and nature.
Indeed, humans heavily populate nearly the entire land mass of the earth.
However, killing is not a fundamental part of our nature, and the
consequences of teaching children (who naturally empathize with and like
animals) to kill innocent creatures has profound implications. We have
become so powerful that we can rapidly change our environments; we can
deplete the topsoil, drain the earth of natural resources, and even change
the climate. Our bodies evolved (or, as some believe, were created by God)
to thrive in a world that is rapidly becoming a remote memory. If humanity
is to thrive, it must live according to its nature, which includes living
harmoniously with other creatures.
