Having said that, there are likely many reasons which contributed to their demise, not the least of which would have been competition with modern humans. It's also probably true to say that some of these ancestors were not so much wiped out as 'absorbed' by us, since we do exhibit some of their DNA in our modern genome.
The fact that we do not know for sure is not a default win for the creationist position. It's simply yet another argument from ignorance.

I would have to agree with you regarding the absorption of earlier hominid populations into that of HSS. while as a whole, the amount of Neanderthal DNA in EurAsian populations is pretty small, 2-4% depending on geographical locale etc... an interesting thing to note is that certain parts of our genome have a very high percentage of Neanderthal genetics. The genes that code for hair type,hair color and skin pigmentation for example have approximately 70% HNS genes whereas other aspects of our code have no HNS influence on them whatsoever. The fact that we were able to breed successfully with HNS and Denisovan is very good evidence that we all have our roots in earlier hominid lines like Erectus or Heidelburgensis and that we are all just one big sub species sharing very close genetic ties. Another anecdote that was a topic of research I did when I was doing my undergrad work was that in the Levantine valley that runs from Northern Israel up into central Lebanon, there are very clear indications that HSS and HNS not only shared the same geographic niche, but lived in the same communities. A really interesting part of that is that they buried their dead together in the same "cemeteries". For that to occur, it would indicate, in my opinion, that the community ties were just the beginning for these two different people and that they very likely shared work and resources as well as familial bonds close enough that they buried their dead together.

obviously you dont understand genetics. HSS can not absorb HNS. The paternal and Maternal lineage can not be absorbed other wise they will stay among current humans. Current humans lineages all go back to that one man (Y chromosomal Adam the MRCA of all curent humans) who lived 20k to 200k years ago.
But since we are at it can you explain to me how billions of early humans (erectus, neanderthals, and all the other names) lived seven million years making 10s of billions of skeletons, died out by the time of the Ancestral Man of Current humans (20-200k years go) leaving only few thousand homosapiens in africa whom only one man of them have sons now. and when the last sons of those homosapiens tribe died out without having sons (give me a guess).
You want to know just how stupid these liars think you are? That tooth was discovered in 1930 to be that of an extinct pig! This subterfuge has continued right up to the 1980′s .

You need to be more clear in your arguments. It's very very difficult to understand what it is exactly that you're saying. I will address your first point however as best as I can. You seem to suggest that Homo Sapiens cannot have absorbed Neanderthal DNA because it would have stayed with current humans--at least I THINK this is what you're saying. However, current non-african humans share 1-4% of their DNA with the Neanderthals, which is highly suggestive of interbreeding, or "absorption" of their genetics. Am I addressing your point correctly?

you did not answer any of my questions.
how did Neanderthal have dna in africans who did not leave africa. The back to africa migration is Maternal haplogroup M in Ethiopia, and Paternal Arabs J1.
subsaharan africa have no back migration. how did they get neanderthal dna in the last 200 000 years.
