Gould has a political agenda, and the way he
treated EO Wilson when Sociobiology came out is
almost unforgivable in a scientist, but that is
not a refutation.

See Gould's book, which you apparently are dismissing
without having read, for Gould's data, which is not
consistent with the reason you have just given.
His data (which he admits is not his data; he does
not claim to be originating the idea, only collecting
together and popularizing data gathered by many
others) involves studies of the changes in species
over time that show that there is no such process
going on as you suggest. To summarize:
At any given time, a species that is at neither the
right wall nor the left wall is roughly equally
likely to get less or more complex. Natural
selection does not tend to increase complexity.
That is Gould's argument.
