One basic need connects all life on earth - the need to breed. But for a few creatures, the odds of success are overwhelmingly stacked against them. Some must find a partner when there are none to be found, while others must find a way to succeed without breeding at all. And some must try and adapt in a world unrecognisable from when they were born. These are animals that have evolved some of the most extraordinary mating strategies of all.
Sir David Attenborough reveals nature's evolutionary anomalies. Here he looks at the platypus and the curious case of the male Midwife Toad.

In the far north of the planet lies the largest land habitat on earth, home to snow-covered forests and the icy open tundra. These are lands of extremes that push animals to their limits: in winter they are so cold that much of the ground has remained frozen since the last ice age. To stand any chance of survival, animals must adapt in extreme ways: here a super pack of wolves, 25 strong, has come together to take on the only large prey available to them in winter, American bison.
For Alaskans, the return of winter brings new and dangerous challenges.
