It happened in 2003 when scientists cloned a bucardo, an Iberian wild goat, that had gone extinct three years earlier, by inserting its DNA (which they got from frozen bucardo skin) into the eggs of an existing goat. The cloned bucardo was born, but then died just ten minutes later.

There are 26 million square kilometers (10 million square miles) of northern land under vegetation. Over the past 30 years 34 to 41% (9 million square kilometers or 3.5 million square miles) have seen increased plant growth while 3 to 5% have seen a decline. The area of enhanced vegetation is comparable in size to the United States not including Alaska and Hawaii.
