Homo sapiens since when?

According to the model in force our species H. sapiens developed in Africa about 200,000 years ago and only 100,000 years ago, I leave this continent to spread in Asia (the theory of 'Out of Africa ").
A discovery in the sediments, dated to 200,000 to 400,000 years, the cave Qesem in Israele ora potrebbe riscrivere questa ricostruzione.
Secondo la ricerca pubblicata nel " Am erican Journal of Physical Anthropology " otto denti fossili recuperati dai sedimenti sono molto simili ai caratteri morfologici dei fossili di Skhul/Qafzeh, considerati le piú antiche testimonianze di H. sapiens (ca. 110.000 anni, Israele) al di fuori del continente africano.

Fig.1. Vista di alcuni dei denti recuperati nella caverna di Qesem, datati a 200.000-400.000 anni. La loro attribuzione a H. sapiens al momento é dubbia, se confermata would be the oldest remains of our species outside of Africa (image HERSHKOVITZ et al. 2010).

If confirmed, this could mean that modern man has developed probably in the Middle East, Africa rather than, sooner than he thought.
However, other experts and the authors of the research, are very cautious - alternatively it is possible that the teeth belonged to the Neanderthal lineage, which is separated 700,000 years ago by ancestors of H. and whose representatives sapiens left Africa earlier. The teeth recovered are not sufficient to clarify the issue, researchers now hope to recover additional fossils from sediments to clarify the membership of species.
