I think some of the confusion is from associating the GA too directly
with different levels of evolving human intelligence.  The power of the
GA is exploiting the adaptive sampling efficiency of selection and
recombination.  The "learning" is actually the process of evolving to
solve the evaluation function -- in nature, that would be survival in
the given environment.  For a human, evolution is associated with
developing the biological "tools" necessary to cope, such as a flexible
mental structure.

On a different level (different representation) John Holland also
theorizes a GA type of processe in actual human learning, wherein
cognitive rules compete for survival and reinforcement in memory
