Animal genetic resources for food and agriculture crop and livestock species in the early neolithic time period changed our human evolution and lifestyles. This ability to control food production led to major demographic, technological, political and military changes. Consecutively, thousands of years of natural and human selection, genetic drift, inbreeding, and crossbreeding have contributed to the diversification of animal genetic resources and increased the variety of environments and production systems that livestock keeping takes place. Relatively few species have been domesticated; out of the world's 148 non-carnivorous species weighing more than 45 kg, only 15 have been successfully domesticated. The proportion of domesticated birds used for food
An Annotated Checklist of the Birds of the Oriental Region An Annotated Checklist of the Birds of the Oriental Region An Annotated Checklist of the Birds of the Oriental Region is a 1996 softback book published by the Oriental Bird Club, and authored by Tim Inskipp, Nigel Lindsey and Will Duckworth. It contains a list of all 2,586 species recorded in the Oriental Bird Club's areas of operation up to the date of publication. This area approximates to that covered by the Oriental zoogeographical region, with the exception that for countries such as China and Pakistan which straddle the Oriental / Palaearctic boundary, the whole country is included; those species
