Well its false anyway, and if coming from Africa Doggerland would not

 Exactly why do you think he sailed from Africa? The DNA matches the
western European hunter gatherers who had be in Europe as long ago as
17,000 years BP.

 The rest of the article is pay walled but if you read other sources there
is waffling on the skin color although 'black' generates better headlines.
Even Wikipedia is more balanced.

 When you're looking for specific alleles of SLC24A5 and SLC45A2 in ancient
DNA there is room for interpretation.

 Chris Stringer's Just So stories may become yesterday's news. Wolpoff and
Caspari challenged that theory about 30 years ago, partially because
Stringer's time line wasn't realistic.
 Perhaps they will revisit the M haplogroup which has long been an anomaly.
The Just So story says L3 left Africa and mutated to M subclades of which
are common in Asia, including the Indian subcontinent.  Except M1, which
is found in North Africa. Did some M people on their way to Japan get
homesick and go back to Africa?

   Note the Wiki also says the phenotype is more typical
   of northern Africa and that the amount of DNA to be
   had kinda left some holes in the analysis.
   I think that as the weather improved a lot of people
   went walkabout - resulting in a many odd mixtures
   that eventually blended into a 'normal'.
   DNA and other ID tech keeps improving, so we're bound
   to find a lot of unexpected relationships and lost
   cousins. Just recently they found remains of what
   was probably the first wave to push into Neanderthal
   occupied Europe ... which, don't appear to have
   made it long-term. Second wave was bigger.
   Oh well, our 'family tree' looks more like an
   unkempt bush ... and nobody is yet sure where
   Erectus fits in as they preferred tropical climes
   and those are terrible for DNA preservation.
   LIKELY some are mixed into the south asian
   population.
