An exploration of the scientific phenomenon known as "adaptive radiation", the way in which a small founding group of a plant or animal species can give rise to a number of new species, and the way in which a new environment encourages this proliferation - Darwin's "natural selection" in action. Oceanic islands are the best places to see the process at work, and the Galapagos provide the best of all demonstrations. The program looks at the many forms of animal and plant life in the islands, with particular attention to the evolution of the species unique to them.

Apart from their external appearance, animals go through behavioural and physiological changes to adapt themselves to different environments: for example, acquiring the ability to drink salt water. Galapagos examples seen in this program include sea lions, sea birds and the marine iguana, a cold-blooded reptile which has adapted itself to endure the cold waters of the sub-Antarctic Humboldt current.

It was not until 1930 that the outside world knew that there were people living in the highlands of Papua, New Guinea. In 1950 the first contact was made with a group of 55,000 Mendi, part of a million inhabitants of the New Guinea highlands, formerly not known to exist. The Australians have since built an airstrip, a hospital, schools, a hotel and other permanent buildings there, but the Mendi have kept their culture intact. A CBC film crew directed by Nancy Archibald has recorded some of the ancient culture and lifestyle of the Mendi and the results are presented in this special one-hour documentary.

Geologic Journey: The Rockies tells the story of the great spine of stone that runs from the Canadian North to the southern United States. As the camera takes the audience on a highwire tour through the peaks of the Rockies – in both Canada and the USA – craggy rock faces and dangerous ice reveal the growth pangs of the mountain building era. The pristine beauty of the Canadian Rockies gives way to the ghost towns and gold mines that litter the mountains in Colorado – a telltale clue to the different geologic forces at work in the Canadian range and their American cousins.
This episode is an illustration of how nothing ever stays the same, not even the Rockies. Despite the appearance of timelessness and permanence, geologists are discovering how these rocks will meet their end – a sobering perspective on time, place and the enormity of the earth’s Geologic Journey.
