study have found that the domestication of dogs start out somewhere around 32 thousand years ago , give or take . Helen Briggs in theBBC articlereported that the process likely started when tolerant wolves snuck into human bivouac to slip food and the connection grew from there . Since Canis familiaris burst from wolves , their agreement of us and our understanding of them has evolve exponentially . But what is it that make dogs so incredibly friendly with us ?
What Makes Dogs Our Best Friends?
Bridgett vonHoldt , prof of evolutionary biology at Princeton , has observe that domestic dogshave a genethat causes them to be hyper societal . The gene are present in the great unwashed as well , but only in those who digest from a condition called Williams - Beuren Syndrome . People with Williams - Beuren are also hyper social and have a trend to love and be friends with everyone , but they lack the genes that are present in hyper societal domestic dog .
When vonHoldt receive the Williams - Beuren genes in wienerwurst genomes , she thought that it might have a connector to dog ’ friendliness toward mass . Her study show a wide variety of changes in the genes , and the hound with the most changes were the most social .
Over metre , those genes have changed and vonHoldt believes that the changes have “ helped turn wolves into human - sleep together pawl . ” Dogs with the least changes to the genes showed independent behavior and were the least concerned in socialise with people .

Dog Behavior vs. Wolf Behavior
The study also involved testing the doings differences between dog conduct and wolf behavior in the bearing of people . Both dogs and Wolf were trained to do a labor and then enquire to execute that job both alone and in the presence of a person , unfamiliar and familiar .
The wolves were raised by people , so they were easy around the flight simulator and would even recognise them but were not concerned in interact with them for a long time , unlike the dog .
Wolves and dogs were both able to easy perform the task alone , but the wolf group outperformed the dogs overall . In the presence of multitude — both familiar and unfamiliar — the wolves did better than domesticated dogs because the dogs were too focussed on the people in the room . It have them longer to complete the undertaking , whereas the wolves finished the labor in nearly the same amount of time as when citizenry were n’t present because they did n’t interact with them .
Our connexion with dogs has been cultivated for thousands of years and this in high spirits level of sociableness was likely selectively engender into them . When tolerant skirt chaser go into human camps it led the direction to people using them for shelter . Those tolerant wolves bred and their materialization were friendlier with mass , and domestication began .
Evolutionary anthropologist Brian Hare trust thatthe study supportedthe “ survival of the friendliest theory of dog tameness . ” The tolerant brute likely had variants of the genes that our dogs have now , and as those genetically modified wolves spawn , “ their fright was replaced by the friendliness and a novel societal partner was create , ” according to Hare .
Though the cogitation was little , vonHoldt believes that the results could head to many other studies focused on the genetics behind the hyper societal behavior of wienerwurst . She and her colleagues did not focus on purebred dogs enough to see if the breed has an result on these cistron , and only studied a select few breeds during the initial report .
This genetic discovery is a big step in the counsel of finally understand the scientific background signal of Canis familiaris tameness . It will take a much wider range of mountains ofdogs and wolvesto get more solid results , but we ’re unaired to see out just what makes dogs our best friends .
