If wild Dog get domesticated does genome change? Answer by Dr. Uma Ramakrishnan during science at sabha 2017 Village dog DNA reveals genetic changes caused by domestication
Dogs were domesticated from wolves tens of thousands of year ago - though what exactly it is, at the genetic level, that distinguishes dogs from wolves, is unclear. Amanda Pendleton and Jeffrey Kidd, authors of a new study in BMC Biology, explain how they utilised new genomics technology - and village dogs - to address this question.
The dog has been man’s best friend for thousands of years, forming a relationship that pre-dates the establishment of agriculture. Domesticated animals, including dogs, share a distinctive collection of traits that distinguish them from their wild ancestors.
Changes in fur color and texture, the shape of ears, tail length and its curvature, eye color, and alterations in facial structure are some traits distinguishing dogs from wolves. Yet, the trait that most importantly differs is behavior. Thousands of years ago, dogs were tamed and domesticated from wolves, which over time yielded animals that were more and more friendly with humans, transforming the once wild creatures into the domestic dogs of today.
With the advent of modern genomics technology, a number of approaches have been used to search for the precise genetic changes that turned wolves into dogs.
Village dogs are essential genetic resources that help us understand dog evolution
We recently participated in a study that that used DNA from ancient dogs that lived among humans to address outstanding questions related to the timing of dog domestication. Ancient DNA technology is a genetic time machine, allowing researchers to directly see genetic variants that existed in the past.
Since domestication involves selection of traits over time, which leads to genetic changes, the science of genomics can identify which genes across an entire genome are altered during this intense artificial selection period
