If you traced your family tree back 185 million generations, you wouldn't be looking at a human, a primate, or even a mammal. You'd be looking at a fish. So where along that line does the first human show up? The answer may surprise you.

Grasslands cover one quarter of all land and support the vast gatherings of wildlife, but to survive here animals must endure the most hostile seasonal changes on the planet. From Asia's bizarre-looking Saiga antelope to the giant anteaters of Brazil, grassland animals have adapted in extraordinary ways to cope with these extremes. In the flooded Okavango, lions take on formidable buffalo in epic battles, on the savannah bee-eaters take advantage of elephants to help catch insects and, on the freezing northern tundra, caribou embark on great migrations shadowed by hungry Arctic wolves.

Elephant poaching worldwide has reached epidemic proportions. In Kenya, the David Sheldrick Wildlife Trust provides a sanctuary for baby elephants who are its greatest victims, left to die without the nurture and protection of their matriarchal herds. In 2010 a baby elephant named Sities was rescued and brought to the Trust’s Nairobi Nursery to begin her rehabilitation. Her remarkable story was followed by audiences worldwide who watched her progress from day one. Now three years later we catch up with Sities, who has reached the age where she can be integrated into the wild elephant herds of Tsavo East National Park. HOW TO BE A WILD ELEPHANT observes the challenges Sities will face as she leaves the safety of the Nursery and moves on to the next phase of her journey back to freedom.
