James,

An interesting read. While I agree with his essential point,
namely that there is no evidence here on Earth for evolutionary
convergence toward human-like intelligence, one cannot conclude
_on_that_basis_ that it will not be found among ETs.

It is often an implicit premise from the biologists' point of
view that intelligence is an 'artifact' of a strictly biological
process. Besides not conceding that, I submit that the 'origin'
of intelligence, human-like or not, is immaterial here.

It is sufficient that at least one example, if not several
examples, arose here in a relatively short time.

In conjunction with the principle of mediocrity and the age of
our planet relative to the universe as a whole, the reasonable
and compelling conclusion is that this phenomenon is by no means
unique to our planet, and is probably widespread, even if
relatively uncommon among the cosmic ensemble of organisms.
