I realise I'm mailing to an empty room, but there you go.....

Maladaptive behaviours do not, in the long run persist. As long as
a species is adequately equipped to survive it will do so, it does not need
to be the most vigourous, the best equipped, it just needs to be equipped
sufficiently. Like the old creationist argument about eyes being too
perfect to have evolved by chance, this ignores the gradual slight changes
over millions of years that led up to humans eyes, which are far from
perfect (goldfish can see further into both the infra red and ultraviolet
than we can). An individual may possibly survive by 'accident' but a
species will not prosper based on luck alone.

But this contradicts your earlier view of superior fit species

? But this is the view you basically presented.
