The Afroasiatic languages, as they are distributed today

The Proto-Afroasiatic homeland is the hypothetical place where speakers of the

Western Asia
.

The contemporary Afroasiatic languages are spoken in West Asia, North Africa, the Horn of Africa, parts of the Sahara and Sahel, and Malta. The various hypotheses for the Afroasiatic homeland are distributed throughout this territory;[1][2][3][4] that is, it is generally assumed that proto-Afroasiatic was spoken in some region where Afroasiatic languages are still spoken today. However, there is disagreement as to which part of the contemporary Afroasiatic speech area corresponds with the original homeland. The majority of scholars today contend that Afroasiatic languages arose somewhere in Northeast Africa.[5]

Date of Proto-Afroasiatic

There is no consensus as to when Proto-Afroasiatic was spoken.[6] The absolute latest date for when Proto-Afroasiatic could have been extant is c. 4000 BCE, after which Egyptian and the Semitic languages are firmly attested. However, in all likelihood these languages began to diverge well before this hard boundary.[7] The estimations offered by scholars as to when Proto-Afroasiatic was spoken vary widely, ranging from 18,000 BCE to 8,000 BC. According to Igor M. Diakonoff (1988: 33n), proto-Afroasiatic was spoken c. 10,000 BC. According to Christopher Ehret (2002: 35–36), proto-Afroasiatic was spoken c. 11,000 BC at the latest, and possibly as early as c. 16,000 BC. These dates are older than dates associated with most other protolanguages.[6] An estimate at the youngest end of this range still makes Afroasiatic the oldest proven language family.[8] Contrasting proposals of an early emergence, Tom Güldemann has argued that less time may have been required for the divergence than is usually assumed, as it is possible for a language to rapidly restructure due to areal contact, with the evolution of Chadic (and likely also Omotic) serving as pertinent examples.[9]

Urheimat hypotheses

No consensus exists as to where proto-Afroasiatic originated. Scholars have proposed locations for the Afroasiatic homeland across Africa and western Asia.

Proto-Cushitic speakers with economic transformations in the Sahara dating c. 8,500 years ago, as well as the speakers of the Proto-Zenati variety of the Berber languages with an expansion across the Maghreb in the 5th century CE.[12] More hypothetical links associate the proto-Afroasiatic-speakers with the Kebaran and the Mushabian culture.[13] Others argue for a possible affiliation between proto-Afroasiatic and the Natufian culture.[6][14][15][16]

The linguistic view on the location of the homeland of Afroasiatic languages is largely divided into proponents for a homeland within Africa, and proponents for a homeland in western Asia. To date, a homeland within Africa is favored by a majority of scholars, although a significant minority of scholars support a homeland in western Asia.[6][7]

Pagani and Crevecoeur (2019) argue that, given the still open debate on the origin of Afroasiatic, the consensus will probably settle on an intermediate "across-the-Sinai" solution. They also note that the very early interactions between African and Eurasian cultures, point "to a geographical shrinking of what can currently be defined as 'strictly African' in a long term perspective."[17]

Western Asian homeland theory

Levant agriculturalists

Supporters of a western Asian origin for Afroasiatic are particularly common among those with a background in Semitic or Egyptological studies,

Natufian Culture, arguing that the reconstructed lexicon of flora and fauna, as well as farming and pastoralist vocabulary indicates that Proto-AA must have been spoken in this area. Scholar Jared Diamond and archaeologist Peter Bellwood have taken up Militarev's arguments as part of their general argument that the spread of linguistic macrofamilies (such as Afroasiatic, Bantu, and Austroasiatic) can be associated with the development of agriculture; they argue that there is clear archaeological support for farming spreading from the Levant into Africa via the Nile valley.[14][16]

Militarev, who linked proto-Afroasiatic to the Levantine

Natufian culture, that preceded the spread of farming technology, believes the language family to be about 10,000 years old. He wrote (Militarev 2002, p. 135) that the "Proto-Afrasian language, on the verge of a split into daughter languages", meaning, in his scenario, into "Cushitic, Omotic, Egyptian, Semitic and Chadic-Berber", "should be roughly dated to the ninth millennium BC". Support for the migration of agricultural populations, according to linguists, are the word for dog (an Asian domesticate) reconstructed to Proto-Afroasiatic[20] as well as words for bow and arrow,[21] which according to some archaeologists spread rapidly across North Africa once they were introduced to North Africa from the Near East, viz. Ounan points.[22]

Lexicon linked to a pastoralist society (cattle-breeding) reconstructed for proto-Afroasiatic also support a western Asian homeland, possibly indicating an earlier pastoralist migration.[23]

Northeast African homeland theory

Afroasiatic languages ca. 500 BC, Omotic and Chadic branches are not shown[24]

A Northeast African homeland has been proposed by the majority of linguists as the origin of the language group because it includes the geographic center of its present distribution and the majority of the diversity observed among the Afroasiatic language family, sometimes considered a telltale sign for a linguistic geographic origin.[5][25] Within this hypothesis there are competing variants.

Red Sea coast

Proposed homeland of the Afroasiatic languages and subsequent migration of the Semitic branch into the Levant
African languages and their place of origin according to Christopher Ehret

Christopher Ehret has proposed the western Red Sea coast from Eritrea to southeastern Egypt. While Ehret disputes Militarev's proposal that Proto-Afroasiatic shows signs of a common farming lexicon, he suggests that early Afroasiatic languages were involved in the even earlier development of intensive food collection in the areas of Ethiopia and Sudan. In other words, he proposes an even older age for Afroasiatic than Militarev, at least 11,000 years old, and believes farming lexicon can only be reconstructed for branches of Afroasiatic. Ehret argues that Proto-Afroasiatic speakers in Northeast Africa developed subsistence patterns of intensive plant collection and pastoralism, giving the population an economic advantage which impelled the expansion of the Afroasiatic languages. He suggests that a Proto-Semitic or Proto-Semito-Berber-speaking population migrated from Northeast Africa to the Levant during the late Paleolithic.[26][27][28][29]

In the next phase, unlike many other authors Ehret proposed an initial split between northern, southern and Omotic. The northern group includes

Chadic stems from Berber
(some other authors group it with southern Afroasiatic languages such as Cushitic ones).

Ethiopia

Roger Blench has proposed a region in the adjacent Horn of Africa, specifically in modern day Ethiopia, arguing that Omotic represents the most basal branch and displays high diversity.[1] Others have however pointed out that Omotic displays strong signs of contact with non-Afroasiatic languages, with some arguing that Omotic should be regarded as an independent language family.[30][31] Like Ehret, Blench accepts that Omotic is part of the Afroasiatic grouping and sees the split of northern languages from Omotic as an important early development. Güldemann (2018) does not accept Omotic as unified group, but argues for at least four distinct groupings.[9]

Sahel/Sahara

Lionel Bender proposed the area near Khartoum, Sudan, at the confluence of the Blue Nile and White Nile.[3][32] The details of his theory are widely cited but controversial, as it involves the proposal that Semitic originated in Ethiopia and crossed to Asia directly from there over the Red Sea.[citation needed

Evidence from population genetics

Autosomal DNA

Scholars, such as Hodgson et al., present archaeogenetic evidence in favor for a place of dispersion within Africa, but argue that the speakers of Proto-Afroasiatic can ultimately be linked to a Paleolithic and pre-agricultural migration wave into Africa from Western Asia, and that the Semitic-branch represents a later back-migration to the Levant.[33]

According to an autosomal DNA research in 2014 on ancient and modern populations, the Afroasiatic languages likely spread across Africa and the Near East by an ancestral population(s) carrying a newly identified "non-African" (Western Eurasian) genetic component, which the researchers dub the "Ethio-Somali" component. This genetic component is most closely related to the "Maghrebi" component and is believed to have diverged from other "non-African (Western Eurasian) ancestries at least 23,000 years ago. The "Ethio-Somali" genetic component is prevalent among modern Afroasiatic-speaking populations, and found at its highest levels among those in the Horn of Africa. On this basis, the researchers suggest that the original Ethio-Somali carrying population(s) probably arrived in the pre-agricultural period (12–23 ka) from the Near East, having crossed over into northeast Africa via the Sinai Peninsula and then split into two, with one branch continuing west across North Africa and the other heading south into the Horn of Africa. They suggest that a descendant population migrated back to the Levant prior to 4000 BC and developed the Semitic branch of Afroasiatic. Later migration from Arabia into the HOA beginning around 3 ka would explain the origin of the Ethiosemitic languages at this time.[34] A similar view has already been proposed earlier, suggesting that the ancestors of Afroasiatic speakers could have been a population originating in the Near East that migrated to Northeast Africa during the Late Palaeolithic with a subset later moving back to the Near East.[35]

Pre-Neolithic and Neolithic migration events in Africa.[36]

Subsequent archaeogenetic studies have corroborated the migrations of Western Eurasian ancestry during the Paleolithic into Africa, becoming the dominant component of Northern Africa since at least 15,000 BCE. The "Maghrebi" component, which gave rise to the Iberomaurusian culture, is described as autochthonous to Northern Africa, related to the Paleolithic Eurasian migration wave, and the characteristic ancestry components of modern Northern Africans along a West-to-East cline, with Northeastern Africans having an additionally higher frequency of a Neolithic Western Asian component associated with the Neolithic expansion.[37]

Genetic research on Afroasiatic-speaking populations revealed strong correlation between the distribution of Afroasiatic languages and the frequency of Northern African/Natufian/Arabian-like ancestry. In contrast Omotic speakers display ancestry mostly distinct from other Afroasiatic-speakers, indicating language shift, or support for the exclusion of Omotic from the Afroasiatic group.[38]

Genetic studies on a specimen of the Savanna Pastoral Neolithic excavated at the Luxmanda site in Tanzania, which has been associated with migrations of Cushitic-speaking peoples and the spread of pastoralism, found that the specimen carried a large proportion of ancestry related to the Pre-Pottery Neolithic culture of the Levant (Natufian), similar to that borne by modern Afroasiatic-speaking populations inhabiting the Horn of Africa. It is suggested that a population related to the Pre-Pottery Neolithic culture of the Levant contributed significantly to historical Eastern African populations represented by the c. 5,000 year old Luxmanda specimen, while modern Cushitic-speaking populations have additional contributions from Dinka-related and "Neolithic Iranian-related" sources. This type of ancestry was later partially replaced by following migration events associated with the Bantu expansion, with Bantu-speaking Eastern Africans having only little ancestry associated with the Pre-Pottery Neolithic culture of the Levant.[39][40]

Y-chromosome evidence

Keita (2008) examined a published Y-chromosome dataset on Afro-Asiatic populations and found that a key lineage

Omotic populations, but stated that this derived from a small, published sample of 12. Keita also wrote that the PN2 mutation was shared by M35 and M2 lineages and this paternal clade originated from East Africa. He concluded that "the genetic data give population profiles that clearly indicate males of African origin, as opposed to being of Asian or European descent" but acknowledged that the biodiversity does not indicate any specific set of skin colors or facial features as populations were subject to microevolutionary pressures.[41]

Fregel summarized that the Y-chromosome diversity of North Africans was compatible with a demic expansion from the Middle East, because the age of common lineages in North Africa (E-M78 and J-304) were relatively recent. The North African pattern of Y-chromosome variation was mostly shaped during the Neolithic period.[42]

Ehret cited genetic evidence which had identified the Horn of Africa as a source of a genetic marker “M35/215” Y-chromosome lineage for a significant population component which moved north from that region into Egypt and the Levant. Ehret argued that this genetic distribution paralleled the spread of the Afrasian language family with the movement of people from the Horn of Africa into Egypt and added a new demic component to the existing population of Egypt 17,000 years ago.[43]

Nostratic hypothesis

The Nostratic language family is a proposed macrofamily grouping together a number of language families including Indo-European, Uralic, Kartvelian, Altaic, Dravidian and in most cases, but not always, Afroasiatic, among some others.[44] Following Pedersen, Illich-Svitych, and Dolgopolsky, most advocates of the theory have included Afroasiatic in Nostratic, though criticisms by Joseph Greenberg and others from the late 1980s onward suggested a reassessment of this position, arguing that Afroasiatic forms a sister language to the Nostratic family.

Cushitic and Semitic, were wider than those seen between any members of the Indo-European family and as wide as some of the differences seen within and between separate language families, for example, Indo-European and Altaic
.

Elamo-Dravidian, and Kartvelian. Similarly, Georgiy Starostin (2002) arrives at a tripartite overall grouping: he considers Afroasiatic, Nostratic and Elamite to be roughly equidistant and more closely related to each other than to anything else.[46] Sergei Starostin's school has now re-included Afroasiatic in a broadly defined Nostratic, while reserving the term Eurasiatic to designate the narrower subgrouping which comprises the rest of the macrofamily. Recent proposals, thus, differ mainly on the precise placement of Dravidian and Kartvelian.[47]

However, the grammatical structure of [Common Semitic] (especially in the verb) is obviously close to that of Common Berbero-Libyan (CBL), as well as to Bedauye. (Bedauye might, quite possibly, be classified as a family distinct from the rest of Kushitic.) The same grammatical isoglosses are somewhat more feebly felt between Semitic and (the other?)

  33. . We hypothesize that a population with substantial Ethio-Somali ancestry could be the proto-Afro-Asiatic speakers. A later migration of a subset of this population back to the Levant before 6 ka would account for a Levantine origin of the Semitic languages [18] and the relatively even distribution of around 7% Ethio-Somali ancestry in all sampled Levantine populations (Table S6). Later migration from Arabia into the HOA beginning around 3 ka would explain the origin of the Ethiosemitic languages at this time [18], the presence of greater Arabian and Eurasian ancestry in the Semitic speaking populations of the HOA (Table 2, S6), and ROLLOFF/ALDER estimates of admixture in HOA populations between 1–5 ka (Table 1). The Ethio-Somali ancestry is found in all admixed HOA ethnic groups, shows little inter-individual variance within these ethnic groups, is estimated to have diverged from all other non-African ancestries by at least 23 ka, and does not carry the unique Arabian lactase persistence allele that arose about 4 ka. Taking into account published mitochondrial, Y chromosome, paleoclimate, and archaeological data, we find that the time of the Ethio-Somali back-to-Africa migration is most likely pre-agricultural.

This result suggests that Iberomaurusian populations in North Africa were related to Paleolithic people in the Levant, but also that migrations of sub-Saharan African origin reached the Maghreb during the Pleistocene.
  38. . Arabian ancestry correlates with the Semitic branch of the Afroasiatic language family (r = 0.774, p = 7.28 × 10−51). The Cushitic branch of the Afroasiatic language family correlates with both Eastern African (r = 0.417, p = 7.17 × 10−12) and Arabian (r = 0.336, p = 5.46 × 10−8) ancestries. This result is consistent with our previous finding that Cushitic ancestry formed by admixture between Nilo-Saharan and Arabian ancestries39. ... Northern African ancestry correlates with the Berber branch of the Afroasiatic language family (r = 0.946, p = 1.48 × 10−122). Arabian and Northern African ancestries are both descended from the lineage that includes all Out of Africa migrants, ... Omotic ancestry correlates with the Omotic languages (r = 0.777, p = 1.40 × 10−51). Thus, the genomic data support the linguistic hypothesis that the Omotic languages are not part of the Afroasiatic family42.
  39. . While these findings show that a Levant-Neolithic-related population made a critical contribution to the ancestry of present-day eastern Africans (Lazaridis et al., 2016), present-day Cushitic speakers such as the Somali cannot be fit simply as having Tanzania_Luxmanda_3100BP ancestry. The best fitting model for the Somali includes Tanzania_Luxmanda_3100BP ancestry, Dinka-related ancestry, and 16% ± 3% Iranian-Neolithic-related ancestry (p = 0.015). This suggests that ancestry related to the Iranian Neolithic appeared in eastern Africa after earlier gene flow related to Levant Neolithic populations, a scenario that is made more plausible by the genetic evidence of admixture of Iranian-Neolithic-related ancestry throughout the Levant by the time of the Bronze Age (Lazaridis et al., 2016) and in ancient Egypt by the Iron Age (Schuenemann et al., 2017). ... However, this lineage appears to have contributed little ancestry to present-day Bantu speakers in eastern Africa, who instead trace their ancestry to a lineage related to present-day western Africans, with additional components related to the Nilotic-speaking Dinka and to the Tanzania_Luxmanda_3100BP pastoralist (see below; Figure 2).

Interestingly, the frequency of E-M81 follows an east to west cline, with the highest frequencies in Morocco and the lowest in Egypt, similar to the results obtained for classical markers. Based on that evidence and contrary to the conclusions drawn from mitochondrial DNA, Arredi et al. (2004) proposed that North African paternal diversity was compatible with a demic expansion from the Middle East. Because the age of E-M81 and other common lineages in North Africa (E-M78 and J-304) were relatively recent, they proposed that the North African pattern of Y-chromosome variation was mostly of Neolithic origin."
