Genetics can define our love for dogs.

Spread the love

Attachment to certain types of animals in humans can be hidden under a certain encrypted genetic code, which predetermines it – some of the conclusions reached by experts from Uppsala University in Sweden, who studied several dozens of twin genomes from Sweden in this context. It is worth noting that despite the rather controversial nature of such a study, it nevertheless indirectly indicates some interesting features as to why some people fundamentally reject the idea of ​​having a dog, while others remain indifferent to this issue – genetics can answer this question.

Researchers in evolutionary biology and history say that man domestication of a dog occurred at least about 15–20 thousand years ago, and since then the idea of ​​having a dog nearby is an integral part of human life, at least in more ancient times. Now the Swedish team of researchers is very interested in why many people deliberately choose dogs as their pets and companions – the whole thing may be hiding in certain patterns of the genome and the genetic code of certain DNA segments.

Researchers came to this conclusion soon after studying the data of more than a hundred twins from Sweden taken from the Swedish Register of Gemini – it turned out that despite a lot of similar genetic moments between twins, the found different genes can play a certain – if not decisive – role in why Many people choose dogs as companions and not other domesticated animals.

It is worth noting that despite the somewhat controversial nature of the new research – already published in the latest issue of the scientific journal Scientific Reports – it somehow echoes the results obtained in the course of the analysis of other, earlier studies. Thus, genetic attachment can be a truly fundamental cause.
