This is a serious question, don't answer with some "ethnics are all chimps" shit
Basically all modern hunans have remnants of denovisian and neanderthal dna, but in africans, (blacks specificaly) neanderthal and denovisian dna is absent.
Is there any other protohuman dna that they have, or are they entirely homosapien?
(I was too lazy to do research)
Recent genetic research shows that the premise that African populations (specifically those in Sub-Saharan Africa) have zero archaic DNA is inaccurate. While they lack the substantial Neanderthal and Denisovan DNA found in non-Africans (1–2%), many West African populations carry significant amounts of DNA from a "ghost" population of archaic hominins.

This means they are not "entirely" Homo sapiens in the strict sense, as they possess archaic contributions, similar to how non-Africans possess Neanderthal/Denisovan contributions.
Here is a breakdown of what that DNA is and how it got there:
1. The "Ghost" Archaic DNA
What is it? Scientists identified that 2% to 19% of the genetic ancestry in four West African populations (including the Yoruba and Mende) comes from an unknown, archaic hominin species that diverged from the human lineage before the Neanderthals.

Why a "Ghost"? It is called a "ghost" because scientists have not found the physical fossils or DNA of this species; they discovered the DNA signal through complex statistical analysis of modern human genomes.

When did it happen? The interbreeding is estimated to have occurred roughly 43,000 to 50,000 years ago, around the same time Neanderthals were interbreeding with modern humans in Eurasia.

Potential Source: Some researchers speculate that this DNA could come from a late-surviving African hominin similar to Homo heidelbergensis or a later intermediate form like the Iwo Eleru skull, which was found in Nigeria and dates back to just 14,000 years ago.

2. Neanderthal DNA in Africans
Recent Discoveries: Early studies assumed Africans had zero Neanderthal DNA. However, recent methods (like IBDmix) have found that many African populations do carry small amounts (approximately 0.3% to 0.5%) of Neanderthal DNA.

Origin: This DNA is not from direct interbreeding in Africa. Instead, it was introduced by "back-to-Africa" migrations, where modern humans who had already interbred with Neanderthals in Eurasia (Eurasian-related ancestry) moved back into Africa, introducing that DNA into the local population.

3. Archaic Y-Chromosome/Lineage
A00 Lineage: In 2013, researchers identified a distinct Y-chromosome lineage (now called A00) in a Cameroonian man that is significantly older than the previously known "mitochondrial eve" or "Y-adam" (~300,000 years old). Some scientists theorize this could be evidence of a very deep, early admixture with an even older hominin species.

Summary of Archaic DNA Patterns
Non-Africans: Primarily possess 1–4% Neanderthal DNA, with some East Asians/Oceanians having additional Denisovan DNA.
Sub-Saharan Africans: Have minimal to no Denisovan DNA. Many have 2–19% of their genome affected by the "ghost" archaic African population, and a small percentage (0.3%+) of Neanderthal DNA from back-migration.

In conclusion, African populations are not archaic themselves; they are Homo sapiens who, like all other modern human populations, experienced interbreeding with other, now-extinct branches of the Homo genus.
