Scene summary
In the savannahs of Kenya, two female northern white rhinos, Nájin and Fatu, munch contentedly on grass. They are the last two known northern white rhinos left on Earth. Their species is functionally extinct— without a male, they can’t reproduce. And yet, there’s still hope to revive the northern white rhino. How can that be? Jan Stejskal dives into the science of reviving a dying species.
