The world of Zootopia is one of the most amazing worlds that anyone would love to live-- at least in if you're an animal; however, there is more to their history than natural instinct. In the beginning, when humans still ruled, animals were just animals. According to Isic from Wastovideo on YouTube, when humans later had to move to space, Mickey Mouse and his Master Yen Sid brought the ecosystem back and the water by using magic. Donald Duck built an ark to keep all the animals safe from the flood, and a sprit was brought to life to bing the plants. Earth was finally habitable for animals (or most of them).
The following animals: Aardvarks, Rabbits, Bears, Monkeys, Apes, Cats, Dogs, Moose, and Rats were the only animals that evolved, while the rest of the animal kingdom didn't. This was the start of the world of Arthur. You might think that it's bad for the animals--it's not. most animals can talk, seen in The Lion King and Bambi, and they started their own monarchy; however, the animals could speak to the animals that were antroperophic because they speak bla be bla bloo in the Arthur world, and animals said humans to the other animals, which concludes to the Hunter from Bambi, the hunter could have been an animal who was hunting. While animals have a hard time in the world of Arthur they have tv shows, Movies, and books that they predict what's going to happen next which is the conclusion to the end of the world of Arthur.
For over a year, animals finally became antroperophic, and they started building a city which is called... you know what... Zootopia! Most of the animals like aardvarks, rabbits, bears, moose, and rats were part of the city, while the others, like cats, dogs, monkeys, and apes had to suffer. But there was still some controversy between the predators and prey. From the start, animals started from normal quadrupeds on a planet with no plants or water, then magic came to bring it all back. Soon a few animals started to evolve while some were still evolving fast and it concluded to the world of Zootopia as we all know it as and that is the evolution of animals from Arthur to Zootopia.
