Animals have always been dependent on the environment in which they lived - had to defend themselves against predators, at the same time being forced to get food and fight to survive. Flying abilities, and exceptional resistance have been really helpful for some of them, while for the others – migrating abilities. The evolution trends are surprising... The expansion includes three add-ons: 1. "Time to Fly" 2. "Continents" 3. Mini add-on "Darwin Day" In the basic version of the game you could create more than 50,000 different animals. Playing only with the "Time to Fly" add-on the number of possible combinations reaches 50 million! That's more than the number of all species living on Earth. But that's not all. Thanks to this expansion there is much more possibilities. Now it’s time to evaluate which species will adapt most to live on land, in the ocean, and in the air!
