The professor describes camouflage in the military. How does what you read support what you heard?
The reading passage describes the evolutionary development of camouflage as used by animals. In order to avoid capture, animals either blend in with their environment or change color. The lecturer then chronicles the relatively recent use of camouflage by the military. Curiously, in the case of armies, humans have been much slower to use camouflage. Not until the mid 1800s, due to high casualties, did the British finally abandon their brightly colored uniforms in favor of khaki ones which blended in with the environment. Just as animals continue to adapt in their use of camouflage, in the same way military uniforms must change as technology evolves.
