'Evidence from rock shelters is available from around 9000 BP when Neolithic pastoralists had expanded “and progressively assimilated more and more of their neighbouring gathering-hunter peoples into their societies”.[42] The Horn of Africa might not be the origin of pastoralism, but the emergence of this lifestyle change in the region is attributable to climate change that forced societies to abandon foraging habits for livestock herding. The Neolithic herders arrived from the Sahara. The period between 5000 BP and 3000 BP represents the mid-Holocene, when aridity induced migrations of prehistoric pastoralists into the Horn of Africa. In the East African highlands pastoralism appeared abruptly around 3000 BP. The appearance of the pastoral population in the highlands might suggest an adaptive response to aridity in the lowlands where resource pressure could have forced some of the less adapted populations to move into wetter ecosystems.[43] During the wetter phase of the climate, pastoral grazing lands expanded, allowing population dispersal, whereas during the dry climate pastoral land use was concentrated around key resources, as depicted in rock art.[44]"
"The various styles of rock art are depictions of human behavior and beliefs. The spread of the animal breed types was from the Horn of Africa to eastern Africa.[71] Following the desiccation of the environment in the Horn between ca. 3000 and 2000 BP, the short horn zebu depicted in the rock art were widely distributed on the western Eritrean plateau and along the coast by the 2nd millennium BP. The type of rock art of this period has the iconographic or style name ‘sorre-Hamakiya.’ Teka[72] reports that the “artistic style of ancient rock art provides the basis for recognizing a particular cultural-historical tradition”. In the common style of rock art referred to as ‘Ethiopian-Arabian’, the main features are “the depiction of humpless bovine in profile with forelimbs and the hind limbs each merged into one thick line”. In rock art caves on the Ethiopia-Sudan border, depictions include rainmaking rituals, showing the complexity of inter-regional relations between different sites as well as expression of shared cultures and differences. [73] Records from eastern Ethiopia and the northern parts of the Horn (the present day Somaliland) show that the rock art depicted domestic species with different art styles. In Somaliland, the rock shelter called Damaline has polychrome paintings depicting sheep, wildlife, snakes, turtles and human figures with arrows. In the rock art in the Gudka Hardhka caves in northern Somaliland, the iconographic representation of a camel confirms the phenomenon of increased aridity.[74] Evidence from archaeological works elsewhere in Eastern Africa shows that the prehistoric pastoral economies had “some resemblance to that of the present inhabitants”.[75] In the eastern Lake Turkana area, depictions in the “middle to the third millennium [BP]” show the presence of both ovicaprids and cattle, but the camel appeared only later. These pastoralists built stone enclosures to protect their livestock in the plains of the Chalbi basin and expanded southwards into the East African Rift valley due to threats by epizootics.[76] Comparisons of the depictions across the region have yielded evidence of inter-regional relationships.[77] The environmental and geographical locations, and therefore spaces, that connected communities, influenced their art, providing evidence of the diffusion of knowledge towards thirst tolerant livestock species.[78]"
