Cattle are central to the lives and diverse cultures of African *** has played a crucial role in providing valuable protein for billions of households and sources of income and employment for producers and other actors in the livestock value *** long-term natural selection of African cattle typically signals signatures in the genome,contributes to high genetic differentiations across *** has enabled them to develop unique adaptive traits to cope with inadequate feed supply,high temperatures,high internal and external parasites,and ***,these unique cattle genetic resources are threatened by indiscriminate cross-breeding,breed replacements with exotic cosmopolitan breeds,and climate change *** there are no functional genomics studies,recent advancements in genotyping and sequencing technologies have identified and annotated limited functional genes and causal variants associated with unique adaptive and economical traits of African cattle *** genome-wide variants serve as candidates for breed improvement and support conservation efforts for endangered cattle breeds against future climate ***,this review plans to collate comprehensive information on the identified selection footprints to support genomic studies in African cattle to confirm the validity of the results and provide a framework for further genetic association and QTL fine mapping studies.

Wild animals and plants have developed a variety of adaptive traits driven by adaptive evolution,an important strategy for species survival and *** the molecular mechanisms of adaptive evolution is the key to understanding species diversification,phenotypic convergence,and inter-species *** the genome sequences of more and more non-model organisms are becoming available,the focus of studies on molecular mechanisms of adaptive evolution has shifted from the candidate gene method to genetic mapping based on genome-wide *** this study,we reviewed the latest research advances in wild animals and plants,focusing on adaptive traits,convergent evolution,and ***,we focused on the adaptive evolution of morphological,behavioral,and physiological ***,we reviewed the phenotypic convergences of life history traits and responding to environmental pressures,and the underlying molecular convergence ***,we summarized the advances of coevolution,including the four main types:mutualism,parasitism,predation and ***,these latest advances greatly increase our understanding of the underlying molecular mechanisms for diverse adaptive traits and species interaction,demonstrating that the development of evolutionary biology has been greatly accelerated by multi-omics ***,we highlighted the emerging trends and future prospects around the above three aspects of adaptive evolution.
