The contempo popularity of "designer" dogs, cats, micro-pigs and other pets may seem to suggest that pet keeping is no more than a fad. Indeed, it is oftentimes assumed that pets are a Western affectation, a weird relic of the working animals kept by communities of the past.
Well-nigh one-half of the households in Britain solitary include some kind of pet; roughly 10m of those are dogs while cats brand upwards some other 10m. Pets cost time and money, and nowadays bring little in the fashion of material benefits. Merely during the 2008 financial crisis, spending on pets remained nigh unaffected, which suggests that for almost owners pets are not a luxury only an integral and deeply loved role of the family.
Some people are into pets, however, while others simply aren't interested. Why is this the case? Information technology is highly probable that our desire for the company of animals actually goes back tens of thousands of years and has played an important part in our evolution. If and so, then genetics might help explain why a love of animals is something some people but don't get.
The wellness question
In recent times, much attention has been devoted to the notion that keeping a domestic dog (or perhaps a cat) tin benefit the possessor'south health in multiple ways – reducing the risk of centre disease, combating loneliness, and alleviating depression and the symptoms of depression and dementia.
Equally I explore in my new book, there are ii bug with these claims. Beginning, there are a similar number of studies that suggest that pets have no or even a slight negative affect on wellness. Second, pet owners don't live any longer than those who have never entertained the idea of having an fauna well-nigh the house, which they should if the claims were true. And even if they were real, these supposed health benefits only apply to today's stressed urbanites, not their hunter-gatherer ancestors, so they cannot be considered as the reason that we began keeping pets in the first place.
The urge to bring animals into our homes is so widespread that it'due south tempting to think of information technology equally a universal feature of human being nature, just not all societies have a tradition of pet-keeping. Even in the West there are plenty of people who feel no particular affinity for animals, whether pets or no.
The pet-keeping habit often runs in families: this was once ascribed to children coming to imitate their parents' lifestyles when they leave home, simply recent enquiry has suggested that it besides has a genetic basis. Some people, whatever their upbringing, seem predisposed to seek out the visitor of animals, others less so.
So the genes that promote pet-keeping may be unique to humans, but they are non universal, suggesting that in the past some societies or individuals – just not all – thrived due to an instinctive rapport with animals.
Pet Deoxyribonucleic acid
The Dna of today'southward domesticated animals reveals that each species separated from its wild counterpart between 15,000 and five,000 years ago, in the late Palaeolithic and Neolithic periods. Yes, this was besides when we started convenance livestock. But it is not easy to run into how this could take been achieved if those first dogs, cats, cattle and pigs were treated every bit mere commodities.
If this were and so, the technologies available would have been inadequate to prevent unwanted interbreeding of domestic and wild stock, which in the early stages would take had ready access to i another, incessantly diluting the genes for "tameness" and thus slowing further domestication to a clamber – or even reversing it. Likewise, periods of famine would as well have encouraged the slaughter of the convenance stock, locally wiping out the "tame" genes entirely.
But if at least some of these early on domestic animals had been treated as pets, physical containment within human habitations would have prevented wild males from having their way with domesticated females; special social status, as afforded to some extant hunter-gatherer pets, would accept inhibited their consumption every bit food. Kept isolated in these ways, the new semi-domesticated animals would have been able to evolve away from their ancestors' wild ways, and get the pliable beasts nosotros know today.
The very same genes which today predispose some people to accept on their commencement true cat or canis familiaris would have spread among those early on farmers. Groups which included people with empathy for animals and an understanding of animal husbandry would have flourished at the expense of those without, who would have had to continue to rely on hunting to obtain meat. Why doesn't everyone feel the aforementioned way? Probably because at some point in history the alternative strategies of stealing domestic animals or enslaving their human carers became viable.
At that place'south a concluding twist to this story: recent studies have shown that affection for pets goes hand-in-manus with concern for the natural world. Information technology seems that people tin be roughly divided into those that feel little affinity for animals or the environment, and those who are predisposed to please in both, adopting pet-keeping as one of the few bachelor outlets in today'due south urbanised society.
As such, pets may help us to reconnect with the globe of nature from which nosotros evolved.
