How did animals become domesticated?
Domestication happens through selective breeding. Individuals that exhibit desirable traits are selected to be bred, and these desirable traits are then passed along to future generations. Wolves were the first animal to be domesticated, sometime between 33,000 and 11,000 years ago.
Why were animals first domesticated and why?
The first animals to be domesticated for food use are thought to be sheep, between 11,000 and 9,000 B.C. in Southwest Asia. Goats followed later around 8,000 BC. Both animals were used for their meat, milk, and coats, and became an integral part of nomadic communities.
What was the original purpose of domestication?
By the beginning of the Holocene from 11,700 years ago, favorable climatic conditions and increasing human populations led to small-scale animal and plant domestication, which allowed humans to augment the food that they were obtaining through hunter-gathering.
What was the first animal tamed by man?
DogDog is regarded as the first animal tamed by early humans.
Why is domesticated animals important?
Domesticated animals such as livestock play a critical role in diversified farming systems, both because they or their products become food and because they cycle nutrients through the farm. Wild animals can help to manage pest populations and contribute to biodiversity.
What is the main reason why dogs started to become domesticated?
Dogs may have become domesticated because our ancestors had more meat than they could eat. During the ice age, hunter-gatherers may have shared any surplus with wolves, which became their pets. The timing and causes of the domestication of dogs are both uncertain.
Where did the domestication of animals begin?
Most experts agree that the first domesticated animals appeared in Mesopotamia.
When were wolves domesticated?
The majority of researchers claim that the first domesticated animals appeared there around 10,000 years ago. Some, however, claim that it happened even earlier, almost 13,000 years ago. They claim that wolves were domesticated then, which led to the development of dogs, which might also be true.

Who conquered Mesopotamia?
Eventually, the region was inhabited by the Sumerians and Akkadians. It was eventually conquered by Alexander the Great, which is a story many should be familiar with.
Why did people start domesticating animals?
It is commonly believed that the reason people started domesticating animals was climatic and environmental changes that occurred around 21,000 years ago. This was during the Last Glacial Maximum period. These changes continue even today. The effect of these changes was that they made obtaining food extremely difficult for people, so they needed to develop new methods of hunting. This was when the first domesticated animals started to appear, and it is strongly believed that the first domesticated animal was the wolf, some 15,000 years ago.

What was the first livestock domesticated?
Once the Neolithic transition happened, many agricultural societies started appearing throughout the continents. This was when the first livestock was domesticated. It included sheep, goats, pigs, and taurine cattle. Two thousand years after that, 9,000 years ago, humped zebu cattle were domesticated in the area that became Pakistan. Pigs had also domesticated in Asia 8,000 years ago. An interesting thing to note is that they were domesticated from wild boar.
What was the result of massive changes in the ecology and evolution of humans and various animal and plant species?
This led to intense livestock domestication, and humans started moving to different parts of the planet to engage in farming and breeding animals.

What is animal domestication?
Animal domestication is what scholars call the millennia-long process that created the mutually beneficial relationship that exists today between animals and humans.
How long has domestication been around?
Not counting the domestic dog, who has been our partner for at least 15,000 years, the animal domestication process started about 12,000 years ago. Over that time, humans have learned to control animal access to food and other necessities of life by changing the behaviors and natures of their wild ancestors.
What are the three pathways of domestication?
prey pathway, or game management: in which actively hunted animals were first managed (cattle, goats, sheep, camelids, reindeer, and swine)
When did domesticated animals start?
Most of the domestic animals familiar to us today were domesticated not long after people began farming and living in permanent settlements, between 8000 and 2500 BC. Domestic dogs are descended from wolves (Canis lupus). Votive figure, Tibet, Early 1900's.
Where did domestic dogs come from?
Domestic dogs are descended from wolves (Canis lupus). Votive figure, Tibet, Early 1900's. Cattle were domesticated more than once, from different branches of the species Bos primigenius, or aurochs. One branch became Bos taurus, the domestic cattle that live in Europe and North America today.
What is the name of the cattle that live in Europe?
One branch became Bos taurus, the domestic cattle that live in Europe and North America today. Another became Bos indicus, the humped cattle shown here. The DNA of domestic horses is very diverse. This suggests they may have been domesticated in more than one place, from several different wild horse populations.
Is the DNA of a horse diverse?
The DNA of domestic horses is very diverse . This suggests they may have been domesticated in more than one place, from several different wild horse populations.
How did domestication occur?
Domestication was likely initiated when humans began to experiment with hunting strategies designed to increase the availability of these prey, perhaps as a response to localized pressure on the supply of the animal. Over time and with the more responsive species, these game-management strategies developed into herd-management strategies that included the sustained multi-generational control over the animals’ movement, feeding, and reproduction. As human interference in the life-cycles of prey animals intensified, the evolutionary pressures for a lack of aggression would have led to an acquisition of the same domestication syndrome traits found in the commensal domesticates.
What were the first animals to be domesticated?
Dogs and sheep were among the first animals to be domesticated. The domestication of animals is the mutual relationship between animals and the humans who have influence on their care and reproduction. Charles Darwin recognized a small number of traits that made domesticated species different from their wild ancestors.
What is domestication in biology?
Domestication has been defined as "a sustained multi-generational, mutualistic relationship in which one organism assumes a significant degree of influence over the reproduction and care of another organism in order to secure a more predictable supply of a resource of interest, and through which the partner organism gains advantage over individuals that remain outside this relationship, thereby benefitting and often increasing the fitness of both the domesticator and the target domesticate ." This definition recognizes both the biological and the cultural components of the domestication process and the effects on both humans and the domesticated animals and plants. All past definitions of domestication have included a relationship between humans with plants and animals, but their differences lay in who was considered as the lead partner in the relationship. This new definition recognizes a mutualistic relationship in which both partners gain benefits. Domestication has vastly enhanced the reproductive output of crop plants, livestock, and pets far beyond that of their wild progenitors. Domesticates have provided humans with resources that they could more predictably and securely control, move, and redistribute, which has been the advantage that had fueled a population explosion of the agro-pastoralists and their spread to all corners of the planet.
How did human selection affect domesticated animals?
One study has concluded that human selection for domestic traits likely counteracted the homogenizing effect of gene flow from wild boars into pigs and created domestication islands in the genome. The same process may also apply to other domesticated animals.
How does domestication affect the brain?
Foxes that had been selectively bred for tameness over 40 years had experienced a significant reduction in cranial height and width and by inference in brain size, which supports the hypothesis that brain-size reduction is an early response to the selective pressure for tameness and lowered reactivity that is the universal feature of animal domestication. The most affected portion of the brain in domestic mammals is the limbic system, which in domestic dogs, pigs, and sheep show a 40% reduction in size compared with their wild species. This portion of the brain regulates endocrine function that influences behaviors such as aggression, wariness, and responses to environmentally induced stress, all attributes which are dramatically affected by domestication.
What are the three main pathways that animals domesticate?
It is proposed that there were three major pathways that most animal domesticates followed into domestication: (1) commensals, adapted to a human niche (e.g., dogs, cats, fowl, possibly pigs); (2) prey animals sought for food (e.g., sheep, goats, cattle, water buffalo, yak, pig, reindeer, llama, alpaca, and turkey); and (3) targeted animals for draft and nonfood resources (e.g., horse, donkey, camel). The dog was the first to be domesticated, and was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. Unlike other domestic species which were primarily selected for production-related traits, dogs were initially selected for their behaviors. The archaeological and genetic data suggest that long-term bidirectional gene flow between wild and domestic stocks – including donkeys, horses, New and Old World camelids, goats, sheep, and pigs – was common. One study has concluded that human selection for domestic traits likely counteracted the homogenizing effect of gene flow from wild boars into pigs and created domestication islands in the genome. The same process may also apply to other domesticated animals.
What is the difference between improvement and domestication traits?
Domestication traits are generally fixed within all domesticates, and were selected during the initial episode of domestication of that animal or plant, whereas improvement traits are present only in a proportion of domesticates, though they may be fixed in individual breeds or regional populations.
