分集
編輯It starts with animals living during the Ice Age. It also shows how humans became top predators and started hunting mammoths on the continent with deadly spears. We also had to compete with other predators like the Short-faced Bear and the Saber-toothed cats. We destroyed them by depleting their food supply, and making them starve to death. Later after realizing what they done to the great beast's demise they hunted not all the time and then there were no more extinctions in the Americas. That wasn't until pioneers from Europe like 克里斯托弗·哥倫布, several 征服者 and lots of horses were brought by the Conquistadors arrived in North America. Howevever horses are returning to the land of which they evolved in. Also inventing the gun, which in North America, was used primarily for hunting big game animals like the bison. By 1893 only 500 wild buffalo remained, marking the end of the megafauna in the Americas.
註：此集中的大部分動物模型來自BBC的另一部紀錄片野性新世界。
本集展示的是人類是怎樣進入澳洲。
It starts with humans populating New Zealand. We encounter the giant moa. We start to see it was harmless. We then discover Haast's eagle, which hunts moas and starts to target us. We then start to steal the moa's giant eggs and go after the adults for food. We then realize we brought a huge amount of animals to extinction. The program has a part with footage of most of the animals shown in the series and starts to ask the question that if we can't live with these monsters, are we not monsters ourselves. The program then ends on 復活節島 about the aftermath of New Zealand's old world with the giant birds gone and forests as so did the early settlers of New Zealand.
