Recent genetic forensic evidence had shown that mankind
started to domesticate dogs not as hunting buddies – but as garbage collectors?

During the start of the 21st Century, the
National Geographic Society had shown evidence – via genetic science – on how
humanity migrated out of that lush prehistoric savannah on the African
continent for which we had evolved and migrated throughout every corner of the
globe. And as of late, recent genetic studies of canis lupus familiaris – also
known as the domestic dog – have shown that the domestication of man’s best
friend is much more recent than previously thought.
Previously accepted conventional wisdom suggests that
mankind first started domesticating the dog from captured wolf pups that are
later trained to be hunting and foraging “assistants” about 30,000 years ago.
But recent genetic forensic evidence obtained by the DNA analysis of the
genetic material of dogs in a study recently conducted by Cambridge University
suggests that the domestication of the dog occurred much more recently – about
11,000 years ago – about the same time when mankind discovered the rudiments of
agriculture and started settling into large communities - a result that
somewhat rewrites the domestication timeline of man’s best friend.
According to Dr. David Sargan of Cambridge University, the
recent DNA-based findings suggest that wolf varieties that were better able to
digest the starches found in wheat, barley and other grain crops first
domesticated by mankind 11,000 or so years ago were the ones that gradually
evolved into the present breeds of domestic dogs. For all intents and purposes,
wolves first start to gradually evolve into dogs in the ancient garbage pits of
the dawn of our agricultural society 11,000 years ago. The findings not only
explain why dogs, until the present day, developed the taste for biscuits while
their wolf cousins have never been partial to such treats. Does this mean that
the real origin story of man’s best friend – the domestic dog - is rather
mundane and somewhat a tad ignoble?
