|5||01 - Variations Under Domestication||Douglas Adams||
in Hitchhiker's guide to the Galaxy tells that
Evolution can create suicidal behavior in living foods
distant in the future.
Such is not the case with ants and bees,
as is sometimes misconceived.
we did train the genes of our cows and sheep to walk
indifferently into the slaughterhouse.
We trained our horses to be as agile or as massive
as we desired.
So we did with our dogs.
We even trained the genes of our cats to dig holes
for their droppings.

|163||02 - Variations Under Nature||Five Senses||
There are countless special senses in Nature.
Bats can see moths in the darkness with their ears.
Migrating birds can see the magnetic fields generated by the poles of the earth,
like geographic lines on a global map.
Certain fish can see the shapes of objects in the water by similar means,
some magnetic, some by the effect of their movement on the echoes of moving water.
Some water predators see their pray by sensing the electricity generated
by it operating its muscles.
Blind people can see the wall marking the edge of a swimming pool by
feeling the water becoming harder to move through.
Senses can be identified, defined as distinct, and named,
only if we can identify the organs that produce the resulting perception,
and only if the process of evolution making them distinct is complete.
Our brain is young and highly variable.
Most blind people do not see the edge of the swimming pool,
but many of them do.
We have many structures still evolving.
It is convenient to digitize the language and talk about having exactly five senses.
It is misleading to compare the vision of blind people to that of the bat,
not because one uses the sense of hearing and the other that of touch,
but because the vision qualities of the bat are distinct and perfected.
As a side note, it is implied by the D. Postulate,
applied to the development of vocabulary,
that words in the language will become distinct and well
separated, much like species and their individual attributes.
As the time scale is much denser in this case,
the language senses have in fact been perfected long ago.

|164||05 - Laws of Variation||Habit Use and Disuse||
It is shown by Charles Darwin how Habit, Use and Disuse
are all used by Natural Selection in a similar manner:
An unused organ or instinct becomes rudimentary over time,
since Natural Selection will not protect that which it has created,
if it is no longer needed for survival.
As extinction is high and it is no longer a part of the Selection Criteria,
it will diminish in its influence given enough generations.
An organ or instinct reliant upon for survival will be watched over closely
to improve upon any slight variation that occurs.
Hair, for example, will automatically fit itself to any
environment given enough generations.
Habit, learned from parents or others,
will also be perfected in the same process
of Natural Selection, thereby implanting "habit genes".
This is how cats learned to use the litter box.
Habit will also disappear with similar ease given enough generations
if the conditions of life so demand.
