Summer has arrived in Alaska. Free of ice, rivers and streams can flow again. This sets the scene for one of the world's greatest migrations, the Alaskan salmon run.
As temperatures hit minus 60 food becomes scarce, and animals such as foxes and hares shed their colourful coats to camouflage themselves in the snow. The end of winter heralds one of the world's greatest feeding frenzies as large ocean predators target the millions of fish who have found refuge in the Gulf of Alaska.

In this final installment to the series, David Attenborough travels to four unique locations about the globe where an abundance of fossilized plant and animal remains have given us a detailed picture of what life could have been like in prehistoric times. Each of the sites experienced its own set of circumstances which enabled it to preserve many perfect specimens for extraction and analysis. Piecing together the collected evidence, paleontologists have been able to determine early animal hierarchies, their diets and their evolutionary paths.

A close-up view of sex, bug-style, as David Attenborough talks viewers through the different ways in which creepy-crawlies reproduce. Size matters for the minuscule male orb spider, creepily sneaking up on its intended and trying to mate without her noticing, while there's no rest for the lothario-like butterfly, which has plenty of notches on its proverbial bedpost. However, the harvestman spider has no use for sex at all, and reproduces by cloning itself.

There is no uncommon sight hanging on the trees of Asian black bears, chipmunks, scurrying about in search of food, as well as the sika deer, gracefully descend to the water to supplement your diet with brown algae. The very presence of deer and deer attracts the largest predator in this region - the Amur tiger. But the world's largest wild cat is also at risk. Poaching and destruction of habitat of tigers in the Ussuri taiga in Russia for many years have created a real threat of extinction of this rare animal.
