How come, after mastering this

How many find pursuit hunting still a viable lifestyle in the modern
world?

Very few. Which is Paul's point.

though the A'piths were not.

So A'piths clearly occupied a different
niche (and different habitats) from later
homo.

How come all hominids before Homo
(as represented by A'piths) went into
extinction -- after so successfully
occupying a distinct niche for a few
million years?

If Homo is ancestral to A'pith then apith did not go extinct, they
evolved into Homo.


Maybe because that niche disappeared

Absurd.

and/or was invaded by other taxa.

This is nothing but a bad excuse for ignoring ecological realities.

The apith taxon that lasted the longest in stratigraphic overlap with
Homo, namely Paranthropus, was also the one with the most extreme
expression of craniodental characters (under the influence of
character displacement to avoid competition?).

Say what? (Gerrit, very often you efforts to sound important leave
you indecipherable.)


Bad evolutionary theorists -- such
as the savanna types (e.g. Leakey)
and the aquatic nuts --  love to indulge
in promiscuous niche-swapping.  It can
'explain' everything, and avoids all need
for thought.

It seems that they are quite unfamiliar
with all of nature, and the fact that taxa
and species prefer to stick to the same
kind of habitat, and ways of life.   They
have no understanding of evolution,
nor of the concept of 'evolutionary
niche'.

Paul's point stands. It's you that is unfamiliar with nature.

If there were no such thing as niche-swapping (shifting would be a
more appropriate term) then the enormous diversity of life on this
planet would be unexplained.

Irrelevant. This is no excuse for the blatant dimwittedness that
comes from anthro-wannabees that have no understand of niche and niche
constraints.

The bipedal hominidae is not a single species and therefore can not be
considered to have had a single niche

Irelevant. You are a turkey. You pretend that you have important
things to say but you never say anything significant. You are
clueless about ecological realities and how to interpret evidence with
respect to these realities.

that remained unchanged from the
most basal member of that clade to its only extant representative. The
morphological change alone within that group is already an argument
against such a position (there is no need for morphological change in
a stable niche).

Hominids experienced group vs. group competition (Actually it's
community vs. community competition) that accelerated hominid
evolution such that we, eventually, became niche independent. This is
not the case for virtually all other species. Hominid communal
selection is unique in the animal world. And this portends other
aspects of hominid uniqueness.
