   The Mungo man DNA was found to be contamination with European modern   
   human DNA.  They literally sequenced the LM3 insert into Chr 11.  This   
   mtDNA insert was obviously made in the ancestors of modern humans while   
   they were still in Africa before the mitochondrial Eve sequence became   
   the only surviving linage of our species.  The Africans took that chr 11   
   sequence with them when they left Africa around 60,000 years ago.  The   
   LM3 insert is not of Neanderthal origin.

   The researchers that produced the original Mungo sequences had their   
   sample contaminated with DNA that was traced back to modern human   
   individuals of European descent.  The contaminating modern human   
   sequence came from Europe.

   When the population bottle neck occurred keeps getting pushed further   
   and further back in time.  It is now believed that it occurred a couple   
   hundred thousand years ago and both African and non African populations   
   were affected by the same event.  Neanderthals did not go extinct until   
   around 30,000 years ago before the glacial maximum around 25,000 years   
   ago.  They went extinct as conditions were getting worse. Toba occurred   
   around the time that Modern humans were leaving Africa for the second   
   time.  There was a bottle neck for this event as only some of the   
   genetic variation in Africa managed to leave, but the population that   
   remained in Africa was not affected by what managed to leave.  The real   
   reduction bottle neck occurred over a hundred thousands years before   
   modern humans left Africa for the second time.   
      
   There could be some evidence of genetics coming back into Africa.  I'm   
   not going to look it up for you, but one of the studies that noted the   
   previous migration out of Africa over 250,000 years ago also had   
   evidence that African genetics was a mix of multiple populations with   
   some of the mixing with a population that had been separated for over   
   800,000 years.  One mix with this population occurred after the first   
   modern human migration out of Africa and before the second.  They   
   speculated that the population had somehow maintained isolation in   
   Africa somehow, but that population could have come back into Africa.   
   It wasn't Denisovan or Neanderthal, but it could have been Homo erectus   
   that left Africa over 800,000 years ago.  The paper estimated that the   
   population would have had to be isolated for around 900,000 years.  My   
   guess is that if they stayed in Africa, it would be likely that they   
   remained an isolated population because they did not have the Chr 2   
   fusion that occurred around that time.  Neanderthals and Denisovans have   
   the Chr 2 fusion that Modern Humans have.

   There is no doubt that there was a population bottleneck at some time,   
   but the populations that we have DNA sequence for (Modern humans,   
   Neanderthals, and Denisovans) were all affected.  It might have occurred
