18,000-year-old puppy discovered in Siberia could be missing link between dogs and wolves

An 18,000-year-old puppy unearthed in Siberia could prove to be the missing link between dogs and wolves, scientists believe.  The puppy was discovered perfectly preserved by permafrost near Yakutsk, eastern Siberia last summer and carbon dating has revealed it has been frozen for around 18,000 years.   Researchers at the Centre for Palaeogenetics in Stockholm, Sweden announced this week that extensive DNA tests have so far been unable to confirm whether the animal was a dog or a wolf.
