We follow Jill Pruetz through the dry Senegalese landscape of Fongoli. Tracking alongside the local troop of critically endangered western chimpanzees, as they walk for miles to find water. Once at the dried riverbed, the chimps dig to find fresher water, this is one of the only groups in the world that does this.

Camille Parmesan gives us an insight into the lives of the climate sensitive Edith's Checkerspot. She tells us the story of how this climatic connection led her to discover a survival pattern across The Rockies. The butterflies were moving up the mountains and away from the equator, seeking environments with cooler climes. This was a key cog in helping reveal the secrets of our changing climate.

On the Galápagos Islands, Greg Lewbart and his team are trying to catch a marine iguana. Their goal is to study the iguana’s unusual adaptation. They have evolved the ability to shrink and regrow their vertebrae in response to changes in food availability. These conditions arises when the Pacific Ocean that is home to the algae they feed on warms, a result of the weather system known as El Niño.
