How to Build a Dog / Lyudmila Trut in Scientific American, 05/17 (Mai 2017)

Public ISBD [article]  inScientific American > 05/17 (Mai 2017) . - p. 64-67 Titre : How to Build a Dog Type de document : texte imprimé Auteurs : Lyudmila Trut ; Lee Alan Dugatkin Année de publication : 2017 Article en page(s) : p. 64-67 Langues : Français (fre) Mots-clés : loups  chiens  évolution  domestication  anglais Résumé : The animal runs toward me, its curly tail wagging and its loving eyes full of joy. It jumps into my arms and nuzzles my face, like a dog. But it is not a dog. It is a fox—a fox that looks and behaves much like a dog. The animal and its close relatives are the result of 58 generations of selective breeding, performed in an attempt to discover in general the secrets of domestication and in particular how humans may have transformed wolves into the first dogs. Note de contenu : Wild wolves were transformed into domesticated dogs in only the past few tens of thousands of years. Humans clearly played a role in the speciation, but the details are lost to history. A six-decade experiment in Siberia has attempted to replay the process by which wolves evolved into dogs. In this work, another canid species—wild foxes—were selected for tameness over dozens of generations. Within a few generations, foxes emerged that behaved like pets and that had physical characteristics associated with domestication, including mottled coats and curly tails.
