It is part of the multiregional arguement that AMHs evolved from Neanderthals in
Europe. Neanderthals did evolve from erectus (or its equivalent in Europe) and
then migrated to the Middle East.

This has been disproved by Santa Luca (1978).

No, as above. Europe (and Africa) could have been isolated for long periods of
time and, unlike in the Far East, they were not able to migrate from their climatic
area (due to the Med.) and so developed to the respective climates.

This, again is the multiregional arguement. This continuity of traits has been
used to support the Continuity models of human evolution rather than the
Replacement models (e.g. the Afro-European Sapiens and Recent African
Evolution Models

These are usually all from Iberia e.g. Zafarraya (Hublin et al., 1995).

The Origins of Humankind site now has a Message Board devoted to the
Neanderthals and we hope to cover these and other Neanderthal based topics
there as well.

Apologies for the length.
