However, over the last thousand years, this mixing took place in an intense way: the genomes of the Pygmy communities today have up to 50% of the genetic material inherited from their farmer neighbours.By questioning the impact of the discovery of agriculture on the history of genetics and demographics in Africa, this work highlights a major question: what phenomenon allowed the development of the ancestors of the Bantus? 0000003640 00000 n Since scans are not currently available to screen readers, please Read Online (Free) relies on page scans, which are not currently available to screen readers. The fact that these two populations coexisted for 4,000 years without mixing genetically reflects their specific socio-economic structures and the special status that the Pygmies have long had in the eyes of their contemporaries. 0000007056 00000 n Nonetheless, arable land and land under permanent crops occupy only about 6 percent of … �@ V �cAJ����k����v̨���)� 0000002609 00000 n endstream 0000006175 00000 n 6, No. 0000003716 00000 n 0000006575 00000 n 0000007689 00000 n 3 0 obj 9 0 obj « Early agriculture in Africa ». 0000003233 00000 n Agricultural expertise spread across all regions, establishing agricultural bases in Africa arounf 3000 BC; expanding the number of plants being cultivated and harvested. <> The height of the wet period occurred between 9000 and 6000 BC. 0000008003 00000 n 0000036623 00000 n 0000006977 00000 n 7 0 obj 0000049743 00000 n 0000006015 00000 n
