Details coastal environments and the effect of tides, of which the highest can be found in the Bay of Fundy in North America. In places, erosion is causing the land to retreat, while in others — such as the tropics — the expansion of mangroves causes it to advance.
First transmitted in 1965. David Attenborough continues his journey along the Zambezi River. This episode begins at Victoria Falls, the largest waterfall in the world. At the foot of the falls, with its moist climate, a wealth of plants and animals can be found, such as hyraxes. To coax the hyraxes out of hiding, David Attenborough illustrates why taking a dog whistle with you while on an African adventure is a very good idea indeed. Other highlights encountered on the way include an estivating lungfish and a herd of elephants washing and dust bathing at a water hole.Further along his journey David Attenborough explores a Portuguese fortress at Tete, believed to have been built over 400 years ago, and assesses the impact of the then newly constructed Kariba Dam, one of the largest dams in the world, on the displaced Tonga people and surrounding countryside.
Professor Richard Fortey investigates the remains of ancient volcanic lake in Germany where stunningly well-preserved fossils of early mammals, giant insects and even perhaps our oldest known ancestor have been found. Among the amazing finds are bats as advanced and sophisticated as anything living today, more than 50-million-years-later; dog-sized 'Dawn' horses, the ancestor of the modern horse; and giant ants as large as a hummingbird.
