The times have changed from the initial estimates, but it is starting to 
look like the population that became the Neandertals and Denisovans in 
Europe and Asia left Africa half a million years ago, maybe out to 
800,000.  The human population in Africa has fluctuated over the last 
150,000 years in some large swings as the ice age was ending, though the 
glacial maximum was only 25,000 years ago.  For some reason we had a 
major population bottle neck around 80,000 years ago.  The Neandertal 
genomes show evidence that their population was also affected and 
crashed around the same time.  For some reason the other apes were not 
as affected and managed to maintain larger effective population sizes 
and so chimps have around 3 times the genetic variation found among the 
modern humans.
Around 60,000 years ago there was a wave of migration out of Africa, so 
there was around 20,000 years for our population in Africa to recover 
before the migration out of Africa, but only a fraction of the 
population left Africa, so there was a loss of variation among the 
migrants that left Africa, and Africans show a greater genetic 
diversity.  Neandertals and Denisovans likely outnumbered the migrants, 
but that doesn't seem to have mattered and though we coexisted with 
Neandertal for another 25,000 years there seems to have been minimal 
interbreeding.  We have identified three instances that they are calling 
pulses of Neandertal genetics into modern humans.  The modern humans 
that made it out to Indonesia seem to have encountered some Denisovans 
and interbred with them, but again the mix is highly one sided and only 
a few percent Denisovan DNA has been retained by some populations.
What it looks like is that Neandertals and Denisovans existed as smaller 
groups than modern humans.  The individuals that we have sequenced are 
more inbred than most modern humans are.  Though we might have been 
inbreeding to the same extent in Ice Age Europe and Asia.  Beats me how 
large a population could be maintained in any given area during that 
time period.

None of the ID perps have had anything worth talking about since they 
started running the bait and switch on their own creationist support 
base in 2002.  IC and Specified complexity predated the bait and switch 
and only the new IDiot law of thermodynamics seems to have been put up 
since, and everyone should know how well that turned out.  You might 
count CSI, but that is just restating Dembski's older specified 
complexity junk.  No one ever got the promised ID science when they 
needed it, and that is apparent to anyone with a brain by this point in 
time.  It has already been more than 3 years since the last bait and 
switch had to go down on both Texas and Louisiana IDiots that wanted to 
teach IDiocy in their public schools.  It is hard to believe that there 
were still IDiots stupid enough to try back in 2013.  The bait and 
switch had already been going down for over a decade by that time.  In 6 
more months it will be 15 years since the ID perps decided to start 
running the bait and switch instead of putting up any ID science.  No 
creationists have ever gotten the ID science all they get is an 
obfuscation scam that doesn't even mention that ID ever existed.
My guess is that no one expects IDiocy to amount to anything at this 
point in time.  The IDiot science society (ISCID) closed their doors and 
quit the ID scam 8 years ago.  Just that fact should be enough for anyone.
