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 Birds of Australia (Gould) The Birds of Australia (Gould) The Birds of Australia was a book written by John Gould and published in seven volumes between 1840 and 1848. It was the first comprehensive survey of the birds of Australia and included descriptions of 681 species, 328 of which were new to science and were first described by Gould. Gould and his wife Elizabeth travelled to Australia from England in 1838 to prepare the book. They spent a little under two years collecting specimens for the book. John travelled widely and made extensive collections of Australian birds and other fauna. Elizabeth, who had illustrated
