This article deals with the history and evolution of Sub-Saharans and Eastern Eurasians in Europe. North African people have been proven by the y-chromosome mitochondrial DNA and autosomes to be Caucasian

Caucasian race

The term Caucasian race has been used to denote the general physical type of some or all of the populations of Europe, North Africa, the Horn of Africa, Western Asia , Central Asia and South Asia...

Y-DNA

In Europe, African Y-DNA chromosomes (which are defined as A, B and sub-Saharan variants of the Eurasian E) are consistently found at frequencies of less than 1% (with the exception of Portugal which may have up to 3% African Y-DNA).
It is a somewhat controversial issue over what an African Y-DNA haplogroup

Haplogroup

In the study of molecular evolution, a haplogroup is a group of similar haplotypes that share a common ancestor having the same single nucleotide polymorphism mutation in both haplotypes. Because a haplogroup consists of similar haplotypes, this is what makes it possible to predict a haplogroup...

Eurasia

Eurasia is a continent or supercontinent comprising the traditional continents of Europe and Asia ; covering about 52,990,000 km2 or about 10.6% of the Earth's surface located primarily in the eastern and northern hemispheres...

n haplogroups such as haplogroup J, E3b, and even haplogroup R (particularly R1B) are often incorrectly labeled as being African because they can be consistently found at a high frequency in the Afro-Asiatic speakers that live in Africa. Genetic studies disprove this for example Haplogroup E3B has been proven by science to have began in the Near East.

Mtdna

African mtDNA (Haplogroup L which is genetically isolated) is rare in Europe although much more common then African Y-DNA. It is most common in Portugal where 5% of people have it, though outside of Portugal it quite rare (consistently lower than 1%). For example, its frequencies run at 0.7% in Finland, 0.4% in Spain, and 0.1% in Ireland. As in Y-DNA many Caucasian mtDNA haplogroups (such as U6 and H1) and also some Eurasian mtDNA haplogroups such as (M1) are often wrongly described as African; probably because they can be found at high frequencies in the Afro-Eurasian speakers who also have a high consistency of Caucasian Y-DNA haplogroups.

Early history

The early history of Eastern Eurasian and African interactions with Europe can be found by the genetics of contemporary European populations. Both populations seem to have had little influence on Europe
In fact less than 1% of Europeans (including Spaniards) have African y-dna or mtDNA
Eastern Eurasian dna is much more common and is represented mostly by the presence of haplogroup N3 in far north east Europe.

Interestingly many African populations have a large proportion of western Eurasian DNA particularly north Africa
which is about 90% western Eurasian the above study is confirmed by y-dna and mtDNA analysis of north Africa for example over 90% of north African men belong to the western Eurasian E3B,J,G, or R1 haplogroups
In sub-Saharan Africa amounts of western Eurasian DNA can be found in speakers of the afro-Asiatic language branch.

African populations in Europe

In modern Europe up to 1% of the population is African (excluding north African) in origin.

Eastern Eurasian populations in Europe

In modern Europe up to 1% of the population is eastern Eurasian in origin.
