enhance the sensing performance of the perceptual organs when entering new and
unnatural environments.
We may just speculate that the eyes of a fish will explore a spectacular view
by using the effective perception that makes it experience its specific surrounding
under water, i.e., in its habitat as seen in Fig. 2.12. Further, how the world above
the surface is seen from below or what the visual sensation is if the fish may appear
in the air, are hypothetical questions that may never be answered.
The human visual eyes are a result of evolution, with specific preferences re-
quired within the surrounding atmosphere, which seems to be an important factor
for the visual state of performance. The light scattered in an interface of air with
specific light conditions, moisture and climate has evolved the human eye into
a fine tuned organ that is effective in the specific environment. However, since
we lately spend more time in artificial short-distance environments, this is proba-
bly changing our future evolution strategy. This direction may also be affected if
future activities are explored, for example into space as seen in Fig. 2.13, where a
new environment probably will interfere with the evolutionary direction and make
lasting impression.
