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.
Why are vultures bald? Why do some orangutans have big cheeks? And if giraffes have long necks to help them reach the highest leaves, why do they mostly eat low-lying shrubs? Embark on a whirlwind tour around the world as we explore some of nature's most-fascinating evolutionary wonders.
In the thick of the jungle of Rwanda's Volcanoes National Park, an infant mountain gorilla has been caught in a snare. If the rope is not removed quickly enough, the young gorilla could lose its hand. In order to remove the snare, a team of veterinarians will first need to sedate the infant's mother. But if the infant screams too much, the three 400-pound adult males that form part of this gorilla group will all attack. Everything must go perfectly, or there's no telling what could happen. And being jungle medicine, things rarely go perfectly. The pioneering group of vets performing this medical intervention is known as Gorilla Doctors. Led by Canadian Mike Cranfield, they work in Rwanda, the Democratic Republic of Congo and Uganda, where the world's last Mountain Gorillas can be found.
David Attenborough visits archaeological sites where fossils were found illustrating the origins of life on earth, in the ocean. For long, evolution worked very slow and species remained primitive, mostly single-cell, alter fractal. Only the invention of sexual reproduction kick-started genetic diversification.
On 12th September 2015, a 30-ton humpback whale breached and landed on Tom Mustill and his friend Charlotte Kinloch as they paddled a sea kayak in Monterey Bay, California. Incredibly, both survived the incident, but the near-death experience haunted documentary maker Tom and left him wondering if the whale was deliberately trying to hurt them. To find the answer, Tom returned to California in 2018 to investigate. Tom meets those who have survived similar hair-raising encounters and the experts who know the whales best. What he discovers raises far bigger questions, not just about what happened that day but also about our relationship with whales and their future alongside us.
