Godt gemt væk et sted i Sibirien kan man finde venlige, fredelige og pjuskede firbenede væsner med logrende haler. Selvom de ligner til forveksling, er de hundelignende væsner faktisk ræve. Deres fredelige måde at opføre sig på er resultatet af et par biologers banebrydende opdrætnings eksperimenter, der på blot et par årtier lykkedes i at overhale årtusinder af evolution. 

"How to Tame a Fox (and Build a Dog)" er den ufattelige sande historie om spændende forskning med uventede resultater.

I 1959 begyndte biologerne Dmitri Belyaev og Lyudmila Trut deres forsøg på at efterligne ulvens evolutionære udvikling til hunden ved at domesticere vilde ræve. I "How to Tame a Fox (and Build a Dog)" skildrer Lyudmila Trut sammen med biolog og videnskabsjournalist Lee Dugati, nøjagtig hvordan deres interessante forsøg forløb.

Forlagets beskrivelse Tucked away in Siberia, there are furry, four-legged creatures with wagging tails and floppy ears that are as docile and friendly as any lapdog. But, despite appearances, these are not dogs--they are foxes. They are the result of the most astonishing experiment in breeding ever undertaken--imagine speeding up thousands of years of evolution into a few decades. In 1959, biologists Dmitri Belyaev and Lyudmila Trut set out to do just that, by starting with a few dozen silver foxes from fox farms in the USSR and attempting to recreate the evolution of wolves into dogs in real time in order to witness the process of domestication. This is the extraordinary, untold story of this remarkable undertaking.

Most accounts of the natural evolution of wolves place it over a span of about 15,000 years, but within a decade, Belyaev and Trut's fox breeding experiments had resulted in puppy-like foxes with floppy ears, piebald spots, and curly tails. Along with these physical changes came genetic and behavioral changes, as well. The foxes were bred using selection criteria for tameness, and with each generation, they became increasingly interested in human companionship. Trut has been there the whole time, and has been the lead scientist on this work since Belyaev's death in 1985, and with Lee Dugatkin, biologist and science writer, she tells the story of the adventure, science, politics, and love behind it all. In How to Tame a Fox, Dugatkin and Trut take us inside this path-breaking experiment in the midst of the brutal winters of Siberia to reveal how scientific history is made and continues to be made today.

To date, fifty-six generations of foxes have been domesticated, and we continue to learn significant lessons from them about the genetic and behavioral evolution of domesticated animals. How to Tame a Fox offers an incredible tale of scientists at work, while also celebrating the deep attachments that have brought humans and animals together throughout time.
