Put all those Victorian lunacies about 'progress' aside: of course evolution is
The first self-replicating 'organisms' all used non-organic energy sources to
maintain their organisational properties. Having thus constructed a conserved
site of energy, that energy becomes a possible source for other possible
organisms to maintain their organisation with.
To do that requires the construction of a means of locomotion.
Locomotory organisms, once evolved, constitute inherently new sources of
organisition-sustaining energy, but to capture it requires something beyond
trial-and-error guided locomotion: it requires perception as a vicarious
at-a-distance system to guide locomotion to a moving target (which is not done
well by trial-and-error, tactilely-controlled, locomotion).
Perceptually-guided locomotion can be further improved if learning mechanisms
are added by evolution to an individual's repertoire of skills.
And so on: as evolution throws up new organisms to take account of the
situation existing at one point in time, it creates new possibilities that can
be exploited. Exploitation is obviously not guaranteed, but implied as
Take the last stage in this process. In my view, non-human higher primates
have some inner mental life that can be described as their having intentional
states. But non-human higher primates appear, as individuals, to be almost
totally oblivious to this property of their conspecifics, and consequently
cannot take it into account as a fact of the world they live in so as to
control their own actions. Humans have evolved so as to take this fact of life
into account: and people wouldn't have 'mindreading skills' if their
environment only consisted of evolved organisms that didn't have 'minds'.
And that is evolutionary progress: adapting to a world in which that world's
contents have been painstakingly constructed to take account of an
ever-so-slightly more complex collection of abilities that were evolved to cope
with the slightly simpler set of facts those solutions were adaptations to.
The first predators didn't require 'mindreading abilities', just
perceptually-guided locomotory abilities. Not surprisingly, it took all of
evolutionary time to make 'mindreading' a) worth having; b) likely; but c) not
I, for one, am glad it happened :-)
