The Evolution Deceit The field of engineering is divided into
many different branches, but its main objective is to make our
daily lives more comfortable, easier and safer. A great many
details we hardly think about are the products of
engineering—designs and technology that have emerged after years
of research, experience, and hard work by well-trained
individuals. For example, the refrigerator that keeps your food
from spoiling was designed by engineers, as were your
television, music set, elevator, watch, car and computer. All
industrial machinery, satellites, spacecraft, and military
technology are the product of engineering, representing the work
and brainpower of a great many people. Just like these designs
that make our lives easier, there are countless designs in the
bodies of living things that make their lives possible at all:
perfectly functioning wings, cells that work like miniaturized
chemical laboratories, infra-red-sensitive eyes that let their
owners see in the dark, thick skin that can withs
