From the article:
---------------------------------------------------------------------------­------
It has recently been discovered that Homo Habilis DID NOT evolve into
Homo Erectus as previously thought. Darwinian evolutionary biology
postulated that Homo Habilis evolved into Homo Erectus, the precurser
to modern man, but it has now come to light that the species lived
side-by-side for hundreds of thousands of years, making such evolution
highly unlikely.

Gee whiz. Why are there still monkeys? Why are there a lot of
species of monkeys? Why are there still great apes, why are there
still three extant different types of great apes? It must have been
impossible for us to have evolved from an ape like ancestor.

Such sound logic seems to have a few holes in it.

I don't know if there are any known cases of it, but the hypothesis
that is being shot down would be the case where one species H. habilis
evolves into another pretty different species without leaving any sub
populations behind or scattered around the earth. It would be a case
of sympatric speciation with the added extinction of the previous
species and would have to involve the entire population in all its
geographic distribution. H. habilis would also have to not have
evolve sub species or species more similar to itself than H. erectus
that survived the extinction of the parent habilis species. I doubt
that anyone thought this scenario very likely.

Has anyone admitted to actually believing such a scenario for the
evolution of H. erectus from H. habilis? I can't recall anyone
advocating such an unlikely scenario and I've been following human
evolution for over 30 years.

Weren't some h. erectus fossils found in Java dated to 50,000 years
ago? By the time they found h. florensiensis, they were talking about
three other human species co-existing with home sap sap: the hobbit,
neanderthals, and h. erectus. It would seem to rather suggest that
homo habilis coexisted with at least some surviving populations of
homo erectus, whether or not the transition was h. erectus -> h,
habilis -> h. sapiens sapiens.

My hypothesis is that Birdnow is not a human, but an ass. While this
hypothesis is falsifiable in principle, the accumulating evidence is
pretty overwhelmingly in support of this model. It is difficult to
imagine what evidence at this point could indicate otherwise.
