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
Memorandum of Understanding on the Conservation of Migratory Birds of Prey in Africa and Eurasia Memorandum of Understanding on the Conservation of Migratory Birds of Prey in Africa and Eurasia The Memorandum of Understanding on the Conservation of Migratory Birds of Prey in Africa and Eurasia (Raptors MoU) is an international, legally non-binding agreement to protect migratory birds of prey. Hawks, eagles, and falcons can function as indicator species of the ecological condition of a region. As they are at the top of the food chain, these species may be among the first to be affected by environmental pressures such as drought, habitat degradation, and the use of pesticides. Monitoring the population trends of birds
