Learn how rain transforms the area into a lush grazing pasture, creating an abundance of food. Moderate weather makes it harder for predators, as prey can migrate further. With plenty of food available, mating and birthing seasons have arrived.
Even after thousands of years of ice crushing the northern hemisphere and temperatures of 20 degrees lower than those of today, many of the great giants of the ice age still walked the earth. It was only when the world had warmed up again that mammoths, woolly rhinos, sabre-toothed cats, giant ground sloths and glyptodonts finally became extinct. Professor Alice Roberts sets off on her last voyage back to the Ice Age to discover why.
Under the waves and tropical sun, each of Hawaii’s volcanic islands host a unique ocean landscape teeming with biodiversity. But one predator reigns supreme – the shark. With 40 species of shark calling these warm waters home, scientists are seeing new animal behavior around every corner. Whitetip reef sharks “sleep” in tight volcanic tunnels. In the deep water, everything is on the menu for the hunting Tiger shark, from birds to Humpback whales. Hopping from island to island, uncover surprising moments of cooperation, rarely seen hunting tactics and striking insights into these predators of the world’s paradise.
Leading experts examine a rock in a crate of finds from an archaeological dig in Africa, which could contain a very rare 200-million-year-old dinosaur skull. The museum staff prepares for the Wildlife Photographer of the Year awards. Other artefacts from the museum featured in this episode include meteorite fragments that are older than the solar system and the oldest complete beetle specimens ever found in the UK.
Gorillas, rhinos, and elephants, three of nature's largest animals, deliver enormous babies. But the immense size of these newborns stands in stark contrast to their vulnerability. Everything from feeding to protection against predators to learning essential life skills falls on one devoted parent: their mothers.
