The comparison of the genomes of domestic goat (Capra hircus) and the wild species of the same genus showed that the first could get from the Kuban tours (Capra caucasica) the variant gene is muc6, which gives a special resistance to intestinal pathogens, reported in Science Advances. This probably increased the chances of domestic goats for survival in crowded conditions, when in the presence of at least one sick animal, all his neighbors are also very quick to become infected.
Goat became one of the first Pets: people kept them now 11,000 years ago. While genetics of their domestication remains poorly studied. It is unclear how varied their genome after a meeting with the person, although it is assumed which specific genes have provided them with easy to digest food xenobiotics (unusual substances in food), increased milk yield and changes in pigmentation (the mountain bezoar goats Capra aegagrus, from which the home does not happen many colors of those that came from their descendants).
Researchers from Denmark, Italy, China and other countries, headed by Yu Jiang (Jiang Yu) from northwestern University of agriculture and forestry compared the genomes of 164 modern domestic goats 52 goats, the age of the remains which a few hundred or thousand years, 24 modern wild goats of different species (Capra sibirica, Capra falconeri, Capra ibex and Capra caucasica) and 4 ancient wild goats (the age of the remains to 47,000 years). The animals were from different populations, and the researchers used it to understand where what types of goats are bred domestic goats. The formation of hybrids between different species of the genus Capra it’s possible: the wild goats and is now easily mate with C. hircus.
