Evolutionary processes occur within an environment through which their
effectiveness is judged, an environment termed an ecosystem. The name ecosystem brings into
focus the fact that living things require a number of conditions to support
life and that when many different species are present, these conditions and
species all form an interrelated system. Within such a system, the
elements often exhibit the characteristics of one or more mechanisms, and each
of the various mechanisms in a system can impact the others’ operations. Hence,
the constituent elements of an ecosystem impact one another, perhaps simply
through their existence or perhaps through the operations of their mechanisms.
The boundary of an ecosystem is formed by the set of characteristics that makes
it distinct from other ecosystems, and it provides a relatively closed space to
constrain the conditions and mechanisms of the living species contained. Within
this space, that is, within the boundaries of an ecosystem, the efficacy of each
mechanism, relative to its supporting conditions and to all other mechanisms,
is judged.
A popular term for the judgment or evaluation process is survival of the fittest. While this expression
might be apt if one delves sufficiently into the meaning of the word fittest, we
will prefer the appellation natural selection. Survival of the fittest may
be construed as meaning that the bigger and more powerful the entity, the more
fit it is to survive (an extreme abuse of the term has been found in the XIXth
Century with the Social Darwinism movement, that took exactly this
understanding to promote supremacist ideas that would foster some of the worst
events of the XXth Century). If that were the case, then one rightly
ponders, “Where are the dinosaurs today?” An atypical, perhaps even cataclysmic
event, can always take a species or a collection of species to the brink of
extinction; perhaps even take them over the brink. In such a case, one might
surmise that if the infrastructure for life itself survived the event, then why
would not the same dominant species re-emerge, albeit slowly, through the same
evolutionary processes that proved to their benefit in ages past? The answer is
found by noting that fittest is a relative term that must be derived on a
case-by-case basis. Its situational definition is constrained within the scope
of an
