The cultural innovations have transformed ecology, there have been plentiful dietary alterations in human evolution and those related to animal domestication. Most commonly, the patterns could be evaluated in cats and dogs.
Scientific researchers have known for a long time that man’s best friend, dogs evolved from the wolf. But they could never define precisely what changed wolfs into our furry buddies, this topic is debatable.
Archaeological testimonies imply that dogs became discernable in appearance from wolves at around 14,000 years ago, however, the genetic imprints suggest common ancestor around 100,000 years ago. This disagreement can be settled if the semblance of domestic animals (wolves/dogs) did not differ from that of free-living wolves until the evolution from cavemen to early stages of agriculture.
Today’s dogs are diverse, their anatomy and sizes; irrespective of their origin. Some breeds, like husky, Pitbull, German shepherd and many more have a striking characteristic for being able to indulge in large meals rapidly, possibly it could be a relic of competitive feeding in wolf. A pack of wolves follow a feeding hierarchy, when they kill a mammal, the alpha wolves – pack leaders feed first, once they are done the remaining young wolves have to compete to feed off what remains.
Swift feeding could be mutation to scavenging during the initial phases of domestication. Dogs who still have this trait become obese if allowed to feed as desired. There is a considerable variation among breeds, some may be prone to such behavior some may not be. The wolves, not afraid of humans ferret out nomadic hunting and with time developed value as guards warning of approaching danger. The danger could other wild animals or hunters or other
nomadic groups. This trait was tuned by artificial selection.
Who would ever think that wolves feeding on milk, curd and fresh vegetables?
The shift of civilization from nomadic age to current trends of industrialization has acted as catalyst in domestication of animals.
1. Early men followed a paleodiet, focused on proteins rather than carbohydrates. They would hunt down wild animals and eat them as their food. Likewise, they would their domestic animals the same. The gut of animals was trough enough to digest the unsurpassable amount of complex proteins.
2. The phase of farming taught men to grow plants, legumes and a lot many vegetables. In addition to meat, men were now feeding onto carbs, proteins and nitrogenous legumes. Whatsoever they were eating, they were feeding the same of their animals. They could now digest nitrogen-rich legumes and complex carbohydrates in grains. The invention of cooking in human world helped
them to cook softer food. The shift in diet encouraged physical and biological changes in the domesticable animals.
3. Industrialization transformed the eating habits of humans drastically. Grains were refined to manufacture new food items, like processed breads, genetically modified fruits and many more…Such a shift brought major transformation among both humans and the domestication of animals. They were now eating more complex carbs changing their digestion abilities. The trajectory of civilization from early age to industrialization has changed the eating habits of animals.
