The wolf (canis lupus) shows attachment to some humans, reveals a study published in Ecology and Evolution. The results of these behavioral tests invalidate the theory that the domestication of the dog (Canis familiaris) would have resulted in their attachment to humans. Three months ago, researchers highlighted the involvement of two populations of wolves, already extinct, in the appearance of the dog that took place between 20,000 and 40,000 years ago. “VSThe behavioral trait likely existed in the ancestral wolf populations from which we domesticated the dog.“, summarizes Science and Future Christina Hansen Wheat, a zoologist and first author of the study.
Distinguish the familiar from the unknown
Proof surpassed by far by the ten gray wolves in the study: like dogs, they recognize familiar people and adopt an attachment behavior towards them. But back to basics: what is attachment? It is defined on an affective dependency, between two individuals, that lasts over time. It is the set of attitudes that the person or animal then adopts to promote closeness. It is observed in particular in infants and the tests to estimate it are also identical.
Raised from 10 days, wolves like dogs, twelve Alaskan huskies, have become accustomed to the company of certain handlers. You may be wondering why the scientists bred the Cubs themselves…Since Previous research has shown that the only way to work with wolves and assess them as we did is to begin hand training before the pups open their eyessays the researcher. This method is also used in other research centers that work with wolves, such as the Wolf Science Center in Austria and several Wolf Centers in the United States.
