The domestic chicken (Gallus gallus domesticus<\/em>) occupies a central role in global agriculture. Although today it is found worldwide, its domestication began in Southeast Asia and the Indian subcontinent around 10,000 years ago. Genetic and archaeological research demonstrates that multiple wild junglefowl species, including Red, Grey, and Ceylon junglefowl, contributed to chicken ancestry through recurrent hybridization and multi-site domestication events.<\/span><\/p>\n

A recent comprehensive review integrates diverse evidence of archaeology, genetics, linguistics, and ethnography to trace how domestic chickens originated and spread into Africa. The methodology collated peer-reviewed studies from PubMed, Web of Science, and Google Scholar, focusing on mitochondrial DNA (mtDNA), microsatellite markers, linguistic etymologies, and archaeological findings.<\/span><\/p>\n

Findings reveal two major introduction waves of chickens into Africa, the first via the Mediterranean route through Egypt during the Ptolemaic period (300 BC), and the second through the Indian Ocean maritime trade networks between the early and mid-1st millennium AD., significant dispersal occurred along the Indian Ocean, as Arabian and Austronesian mariners transported chickens along the East African coast. These voyages also introduced distinct genetic traits of chickens, which are adapted to tropical conditions. After these primary introductions, chickens spread within Africa overland, crossing the Sahara and dispersing across the Horn and West Africa. The result is a rich mosaic of African chicken ecotypes genetically adapted to local environments.<\/span><\/p>\n

Dispersal means of domesticated and their introduction to Africa<\/span><\/p>\n

Genetic studies reveal the diversity and admixture in African chicken populations that exhibit varied maternal haplotypes tracing back to Asia, Europe, and the Middle East. Haplogroups A and D are widespread, with haplogroup D dominant across most regions and A concentrated in East Africa, likely reflecting maritime origins from Southeast Asia, especially linked to Austronesian migration to Madagascar. Other less common haplogroups (B, C, E) may reflect recent introductions of commercial breeds or further historical gene flow from Asia. These diverse lineages highlight the importance of conserving indigenous African chicken varieties. Such breeds harbour adaptive traits, such as heat tolerance, disease resistance, and unique morphological features, critical for resilience to future environmental and socioeconomic changes.<\/span><\/p>\n

Furthermore, chickens fulfill multiple roles in African communities as sources of protein, income, and sociocultural symbols. Ethnographic and linguistic analyses confirm that chickens integrate deeply into rituals, social customs, and languages across regions. Their persistent economic and ceremonial presence indicates a longstanding and potentially earlier and more complex history of domestication and integration than archaeological records alone suggest.<\/span><\/p>\n

The genetic diversity resulting from this history offers valuable resources for sustainable development and adaptation. To harness these benefits, it is recommended to expand genetic profiling efforts using whole-genome sequencing across Africa. Beyond historical and genetic insights, the study explores the broader socio-economic roles of chickens in African societies, linking them to cultural rituals, household economies, and women’s income generation. Such ethnographic and linguistic evidence emphasizes how chickens are interwoven into African livelihoods and identity.<\/span><\/p>\n

By interweaving historical, genetic, and cultural perspectives, this synthesis underlines the multifaceted legacy of domestic chickens in Africa and charts a path forward for leveraging their genetic heritage for climate resilience, food security, and rural livelihoods. Implementing community-based conservation strategies to preserve local chicken ecotypes and biodiversity is highly recommended.<\/span><\/p>\n
