Human beings are animals. We breathe,
eat and digest, and reproduce the same life {{U}}(21) {{/U}}common to
all animals. In a biological laboratory rats, monkeys, and humans seem very much
the same. However, biological understanding is not enough:
{{U}}(22) {{/U}} itself, it can never tell us what human beings are.
{{U}}(23) {{/U}}to our physical equipment the naked human body--we are
not an {{U}}(24) {{/U}}animal. We are tropical creatures, {{U}}(25)
{{/U}} hairless and sensitive to cold. We are not fast and have neither
claws nor sharp teeth to defend ourselves. We need a lot of food but have almost
no physical equipment to help us get it. In the purely physical{{U}} (26)
{{/U}}, our species seems a poor {{U}}(27) {{/U}}for
survival. But we have survived--survived and multiplied and
{{U}}(28) {{/U}}the earth. Some day we will have a{{U}} (29)
{{/U}} living on the moon, a place with neither air nor water and with
temperatures that turn gases into solids. How can we have done all these things?
Part of the answer is physical. {{U}}(30) {{/U}}its limitations, our
physical equipment has some important {{U}}(31) {{/U}}. We have
excellent vision and hands that can {{U}}(30) {{/U}}objects with a
precision unmatched by any other {{U}}(33) {{/U}}. Most importantly, we
have a large brain with an almost {{U}}(34) {{/U}} number of neural
{{U}}(35) {{/U}}.
