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.

Pouch laminator Pouch laminators are designed for moderate use in the office or home. For continuous, large-volume lamination projects, a roll laminator performs more efficiently. Pouches can be bought with different thicknesses in micrometres. Standard home or office machines normally use 80–250 micrometre pouches, depending on the quality of the machine. The thicker the pouch, the higher the cost. Pouches can also measured in mil, which equals one thousandth of an inch. The most common pouch thicknesses are 3, 5, 7 and 10 mil (76,127,178 and 254 μm). Certain pouches such as butterfly pouches can be used with a pouch laminator to
