'HUMAN' MIGRATION

But we are talking about "when it happens"...How is ,i beleive ,complex mix of doers...and the timing is also essential...

                 But we need date.year. when first ape "decide" to be human...Like scouts honest...will not hung on trees anymore..

I dont think there is any real solid evidence to suggest that Neanderthals and humans interbred, and if they did, their offspring probably would not have been able to reproduce (much like how a horse and a donkey can produce a mule, but mules themselves cannot reproduce).

Human communities always expell units that have not match with ordinary member look or behaviour...all mutations good or bad were not always accepted in early tribal communities.And we have to accept that law of incest dates from closest past in our human known history.People that were result of  incest and abnormal were expelled from communities...Neandertals and hobbits are part of some evolution but still Is not clear, were they expelled like "unordinary" trials ,that have mixed among themself centuries ago or those types are straight line from very beggining of humanity?We are looking for the links before...People we have homo sapiens for milions of years and  deviations on which we have to devalve his existance...
And incest like we know today was not always someones will...Lions population was once almost wiped out...and have a "incest" period of reproduction that damages the sperm of lions...they beleive that is reason that they have low reproductive efficiency...

  I agree, maybe a few interbred, ...I see conflict between them, <> different peoples, as we see in History

very interesting...does not incest today usually end up in a 'bad' mutation??---

Concerning incest! Actually a lot of it depends upon your definition of incest. There have been studies of some family units, that have practiced a form of incest over several generations whereby there were no regressive traits in appearance.

And if one considers that third and fouth cousins are OK, then there is this study;

Now, as to whether or not long term incest (10 generations or more) might well produce regressive traits is another story?

But, I would suggest that if the original couple carried few or no regressive traits, then there exists the reality that over a number of generations the children of this admixture seems to breed true!

that do not means always bad mutations...white colour once was "abnormal",like picture from cave says that...members with this "abnormalities" were also expelled out of communities..
  Invisible part that suffers is immune system...That happens to Dare devil...tasmanian....

That means that abnormal means mutation,someone that do not match with look and behaviour of majority...unfortunately...but abnormal do not means always that this mutation will not be advance in the future,first bird with wings,look abnormal but...

Your statement above seems to border upon racism! Is that your aim?

Based upon the above (if it is correct?), I then, rest my case! Concerning, that is, my mention that some science believes that the Neanderthals merely were merged into modern mankind!
