Domestic dog origins challenged - what about man?

The suggestion that the domestic dog originated in East Asia has been challenged.
The huge genetic diversity of dogs found in East Asia had led many scientists to conclude that domestication began there.
But new research published in the journal PNAS shows the DNA of dogs in African villages is just as varied.
An international group of researchers analysed blood samples from dogs in Egypt, Uganda and Namibia.
Today's dogs are descended from Eurasian grey wolves, domesticated between 15,000 and 40,000 years ago.
The point is that I even doubt the claim that mans ancestry is tied to Africa, that in fact man real ancestory is related to the sea and evolution on more than one continent and one source. The verid diversity of races to me shows proof like the wolf and domesticated dog one single source will not be found.
I feel that eventually DNA will lead to discoveries that will throw understanding of the origination of man as thought to day completely out of the window (so to speak).
We came from different apes and the only genetic link is the evolution of a sea creature that became amphibious. The evolution that created the ape leading to the species called man that has like dogs followed a similar path on differing continents.
However I am no expert but its my opinion that to me seems more logic than the african theory.

This new story stirred up an old suspicion that the theory of man evolving from only Africa is not true, I suspect it more complicated than that now accepted opinion.
