Life of Mammals - A Winning Design

The evolution of mammals, roughly about one hundred million years ago, has given rise to varieties of species capable of filling up virtually every niche on earth, from the hospitable environment of the jungle to the desert, the icy poles, the oceans and even the air. In the first episode of this documentary series, Sir David Attenborough takes us on a journey to learn more about these warm-bloodied creatures, starting with the peculiar and fascinating evolution of marsupials in Australia and South America, and moving on to the more familiar placental varieties to which we ourselves belong, showing in the process the implications to which these different adaptations have lead.

In case you're wondering, yes, there will be koalas, kangaroos and platypuses...
