Which sentence is the LEAST relevant to this paragraph?

In 2012, an 11 year-old boy named Jenya was traveling in the woods near his home in Russia when he stumbled across a young, six-foot tall woolly mammoth encased in ice. Jenya reported his find and scientists rushed in to recover the prehistoric relic. Using hammers, shovels, and a special machine to produce heat, they worked for a week to release the remains. When they finally examined the find, they were amazed. This mammoth—named Jenya after its discoverer—was heralded as one of the best-preserved mammoths ever discovered. It gave a one-of-a-kind look at how a living mammoth would have appeared.

Which sentence is LEAST relevant to the paragraph?

The woolly mammoth, an ancestor of the modern-day elephant, thrived millions of years ago. When it first appeared, the world was very different than it is today. Much of the land was frozen, which is why the mammoth needed its thick, warm coat of shaggy hair. Despite the cold, there was a great deal of vegetation, which the huge animals ate abundantly. Mammoths were well suited for their environment. Their population thrived in many of the coldest places of the world, such as Alaska and Siberia.
