Out of Africa, back to Africa, out again?

Update: John Hawks comments.

An article published today in the Daily Mail proclaims "Ancient skeletons discovered in Georgia threaten to overturn the theory of human evolution":
The first Dmanisi fossils were found in 2001. The most recent has only just been unearthed and its details have yet to be published in a scientific journal.

Prof Lordkipanidze said the Dmanisi bones may have belonged to an early Homo erectus which lived in Georgia before moving on to the rest of Europe.

Or the early humans may then have returned to Africa, eventually giving rise to our own species, Homoe sapiens, he said.

'The question is whether Homo erectus orginated in Africa or Eurasia, and if in Eurasia, did we have vice-versa migrations? This idea looked very stupid a few years ago, but not today,' he told the British Science Festival.
This scenario is not contradicted by modern human Y or mtDNA phylogenetics, which say nothing about where the ancestors of modern humans lived prior to the time when these uniparental lineages coalesce (80,000-160,000 years ago).
