Chris Packham returns to BBC Two with Animal Einsteins, a series exploring the remarkable intelligence of the natural world. In the latest episode, the presenter turns his attention to nature's builders, examining the ingenious ways animals construct their homes and habitats.
The programme showcases a range of species with extraordinary engineering skills. Beavers, described as 'super-sized, semi-aquatic rodents', are the only animals other than humans to build dams, with the longest such structure visible from space. The episode also highlights the spider's ability to produce up to seven different types of silk, the hexagonal precision of beeswax explained by the 'honeycomb conjecture', and the intricate nests of long-tailed tits, woven from spider silk and lined with feathers.
Packham also explores biomimicry, where human design is inspired by nature. He visits the alpine house at Kew Gardens, whose low-energy cooling system was modelled on termite mounds. The fungus within the mounds helps keep termites cool by effectively 'breathing' for them, a concept that has influenced sustainable architecture.
While the episode includes laboratory simulations and interviews with scientists, Packham's enthusiasm brings a soothing quality to the science. The show offers a welcome escape, celebrating the ingenuity of the natural world without the weight of current events.
