Time will tell on that. There may not ever be another census, and this kind of thing would depend on who was in power.

I understand yearly "snapshots" may be the future. What they contain being unknown.

It just isn't true. There has been a continual flow of people.

You probably consider yourself Anglo-Saxon, but they were all immigrants too.

That you use the Neanderthals being wiped out by Homo Sapiens as your analogy says all that needs to be said. We are all Homo Sapiens! Our DNA is 99.9% identical wherever we come from, or what our skin colour might be.

I guess they didn't have any dough

I would have to do some research to substantiate my impressions, which are based on my own knowledge of the situation in our local hospitals.

I am aware of some Eastern Europeans who have stayed under the special scheme we set up, but no new arrivals at all, whilst huge numbers from Africa and Asia are being recruited.

It is absolutely true. The existing population absorbed relatively large numbers of people in the past which heavily impacted on their makeup and way of life. The precise details are unknown but the genetic studies tell of huge change but not total replacement.

You do not grasp simple concepts. That is me being as polite as I can when dealing with such wilful stupidity.

I am mostly English/North Western European. Over 70%. My genes say so. I also have genes from Scotland and Scandinavia, Germanic Europe and Wales in much smaller amounts. That is because, like most other people in England, my heritage is mostly from people that have been here for hundreds if not thousands of years.
That is only possible because of little change in the gene pool over many generations.

Compare that to a change of 25% in demographics in one lifetime, when the population is far bigger than at any time in the past.

Are you getting it yet?

Neanderthals are gone, all but for a few percent of their genetic leftovers. That happened became their lands were invaded by humans in relatively large numbers. There was a tipping point where they were simply outbred.
That is where we are heading sooner than you think.

Not that you think very much.

You say one thing, then prove another! It cannot be true if you base, as you do, your theory on the nonsensical concept of "total replacement". You now accept huge change. All we are witnessing today is what is happening in every aspect of life. Everything is going faster. Including people becoming absorbed into their new environments, We won't be "replaced". We will be changed as we absorb the new. Just as we always have been.

So what if the gene pool is now deeper and wider! That's only because the world is smaller and travel easier. We all come from the same pool. Every European could ultimately trace their origins back to Africa. We are all the same. The demographics of the new arrivals may well have been different on arrival, they are generally younger for example, but they will even out over time as they get absorbed. You appear to think everything is set in stone, but if that wasn't true in the past, why on earth will it be now?

Neanderthals were not our ancestors. They were a completely different branch of the human family, a subspecies. To compare what happened to them, to what you expect will happen to us, is a ridiculous insult to all modern humans. They weren't "outbred". They died out, but exactly why, whether by inter-breeding, disease or war, isn't known.

I hope you are beginning to "get it", but somehow I doubt it.
