In this Chapter Dawkins proposes several theories on
the evolution of species and how animals such as ants and birds have developed
as societies. In every example of the animal kingdom Dawkins cleverly proved
his point and defended his selfish gene theory. For instance, when certain
organism give alarm calls to the rest of the group, the theory states “genes
have to come up with a convincing advantage of giving alarm calls which is big enough
to counteract this danger (of being spotted and eaten by the predator)” (169).
In every case presented the theory was proven right and apparently nature has
no space for self-sacrificing beings, at least not if they intend to transmit
their genetic information. After all what would a survival machine be for if it
willingly sacrifices itself for the benefit of another.
As the
chapter develops Dawkins presents a complex situation that may serve as a
starting point for our capacities to deceive. In Dawkins scenario, a population
is composed a species that behaves in three distinct patters: indiscriminant helpers,
those who get help but don’t help back and those who help everyone except those
who denied them help. The first are called Suckers, the latter Cheaters and the
last Grudgers. It is very easy to compare these behaviors with our daily life
where we meet many people who get our help, but do not help us when we need it
or not as much as we expected they would. In fact, it relates very closely to
our society where very commonly partnerships do not work, since one partner may
be doing everything while the other does nothing. In the real world that can be
a problem if it gets known you “cheat” on those who help you, or you simply
never work. It is the hard workers who know who to work and avoid being “cheated”,
who ideally should succeed the most. At least, that is how it works in nature
or how it did with the Suckers, the Cheaters and the Grudges. The first died
exploited by the Cheaters who never paid their favors, yet when the Cheaters no
longer had their naïve relatives around Grudgers refused to help and eventually
Cheaters got extinct as well. Ultimately, in nature it is no use being indiscriminately
altruistic, or indiscriminately selfish. Because the Grudges are selfish nonetheless,
as they feel the necessity to remove a poisonous parasite in the future, in
Dawkins specific scenario, is more important than the energy they waste helping
a “partner” who has it at the present time. It is all a cost versus gain
relationship. The genes will always thrive for the most gain at the least
expense to propagate themselves. That’s what all “the selfish gene theory” is
about.
Moreover,
Dawkins defines the relationship employed by Grudgers, and other organisms such
as cleaner fish with other big fish as symbiosis. A relationship where two
species or two organisms from the same species benefit mutually, or reciprocal
altruism as explained in the above paragraph. Dawkins explains that possibly
our brains’ complexity revolves around the idea of symbiotic relationships. That
feelings like “envy, gratitude, guilt, sympathy” came from natural selection to
avoid being cheated, cheat more effectively or not to be confused with a cheat
(188). This hypothesis implies many things, one of the most impacting ones is
that ultimately our brain’s great processing is: without being cheated, to
cheat as much as possible and without being caught cheating. So as cheaters got
more effective, so did Grudgers at recognizing them; hence slowly each organism
got more sophisticated at getting the most out of reciprocal altruism. This
hypothesis contradicts the “ideal society” proposal or that of a good
community, where everyone knows that may help everyone without getting cheated.
However, someone always takes advantage of what will be called today “Suckers”,
yet if no altruism exists inevitably our societies will collapse. If trust
cannot be developed in things as sensitive as representation then a country may
not function well, if reciprocal altruism does not exist then the whole
structure on which we live cannot function properly. For instance, a President
has the responsibility to meet his country’s needs if he takes advantage of his
power to enrich himself then the country won’t progress. Resulting in the
overall detriment of the community; altruism or at least reciprocal altruism are
essential to the survival of our species.
