Malaysian and Andamanese Negritos don't.
Which is most likely what happened, IMO. Descendants of that population got outcompeted by later ooA migrations, other than small pockets such as Negritos, who also show high Neandertal DNA %.
As for your claim, you're mostly right. There was an incursion of non-African DNA into Subsaharan Africa around 3000kya, probably related to Bronze Age Collapse and migrations around it. Because of this, Africans can carry up to 25% Eurasian DNA, and part of that is Neandertal.
As for the later stages,:
Sapiens or proto-Sapiens interbred with Neanderthals even earlier than the widely accepted cca 40kya admixture date; somewhere between 430kya and 270kya Sapiens dna enters Neandertal genome. While most of it was eventually bred out, mtDNA remained and all later Neandertal populations carried Sapiens mtDNA, with their original mtDNA disappearing
The reason for noncongruent out of Africa migration dates is that at least two occurred; other than the generally accepted cca 70kya migration, there was an earlier one which was limited to coastal areas of Arab peninsula, Indian subcontinent and SE Asia until it reached the previously unpopulated area behind the Wallace line, where it resulted in PNG and Australian aboriginal populations.
The reason for coastal-only migration until PNG was that those areas were already inhabited by Neanderthals and Denisovans whom Sapiens was unable to outcompete.
Only after Toba eruption (75kya) do those populations become weakened enough for Sapiens to outcompete them and that's when we see first successful migration to Middle East.
When Croatia was scheduled to join EU in July 2013., in the run up to that date its government gave out fat subsidies to anyone who converted their land into a wineyard, because once they joined the EU, game over.
That's why they're fine with their salary being less than federal minimum.
Google killed the xmpp momentum by gettimg scared of Facebook around 2010. and adopting the 'walled garden' approach.
