Recently you may have heard stories in the news around newly birthed pups that are modern-day dire wolves, a species of canine that went extinct around 10,000 years ago. You also may have heard about efforts to bring back woolly mammoths who also went extinct several thousand years ago. 

We explore the topic of de-extinction projects like these. We look at some of the reasons that supporters argue in favor of these projects, especially when they involve species that have gone extinct due to human activity. We also look at how the technology used in these projects can be used to help repopulate species that are endangered and how they can help revitalize these vulnerable populations.
