[Some people reminded me that Muntz was working in South America before the events of Ratatouille.

Well, many must have seen that the Sant posted on the Pixar deal, right? However, I've been checking, and found a translated version of the original material (which, in fact, called The Pixar teory) better than the AhNegão because they forgot the Toy Store (think anyone remembered). So, without rolling, here we go:
This theory covers all productions of Pixar since Toy Story, including: A Bug's Life, Toy Story 2, Monsters, Inc., Finding Nemo, The Incredibles, Cars, Ratatouille, Wall-E, watch naruto shippuden movie 5 Up, Toy Story 3, Cars 2, and Valente Monsters University.
Valente is the first and last film in the timeline. Obviously, this film about a Scottish kingdom during the Middle Ages presents the oldest scenario presented in Pixar productions, but is the only one that explains why animals watch naruto shippuden movie 5 behave as humans from time to time in Pixar productions.
In Valente, the Merida discovers that there is a "magic" that can solve their problems, but unwittingly become his mother into a bear. We found that magic comes from a weird witch apparently linked to the mysterious watch naruto shippuden movie 5 flames foxfire present in production. We not only see animals behaving like humans, but we also see brooms (inanimate objects) acting like people in the Witch House.
We also discovered that this witch inexplicably disappears every time through doors, making us believe that she may not even exist. Take it easy, I'll be back to Valente. For now, let the record that the witch is someone we know of another movie this timeline.
[Some people reminded me that animals in Valente gradually stop acting like humans, putting into question the idea that this is the origin of this behavior. My answer is simple. They regress because the magic wears off. Over time, the intelligence evolves naturally.]
There are two lines of evolution: one animal and another artificial intelligences. The events of the following films feature a power struggle between humans, animals and machines. With regard to animals, the course of this conflict is presented chronologically in Ratatouille, Finding Nemo and Up. Notice that no mention Bug's Life, but then explain why.
Ratatouille see in animals experiencing this humanization in smaller and controlled conditions. Remy wants to cook something that only humans do. It creates a relationship with a small group of humans and gets along. Meanwhile, the film's villain, Chef Skinner disappears. watch naruto shippuden movie 5 What happened to him? What did he do with his discovery that animals are able to transcend their instincts and perform watch naruto shippuden movie 5 tasks better than humans do?
It is possible that Charles Muntz, the antagonist of Up, has been heard about this rumor and had the idea for his intentions to expose the thoughts of animals, like their dogs by their collars translation. These necklaces to Muntz showed that animals are smarter watch naruto shippuden movie 5 and even human-like than we thought. He needed this technology to find the exotic bird for which he was obsessed, until he gets to mention the several dogs that has lost since his arrival in South America.
However, after the death of Muntz, Doug and his other experiments are free and do not know the implications of it, but we know that there is growing animosity between watch naruto shippuden movie 5 animals and humans. Now that humans have discovered the potential of the animals, they begin to dare. To develop new technologies, humans start an industrial revolution mentioned in Up.
[Some people reminded me that Muntz was working in South America before the events of Ratatouille. True, but is not explicitly told when and how he began to develop the necklaces. Another thing: we know that Ratatouille is set just before the Up for several reasons. In Toy Story 3, a postcard on Andy's wall has the name and address of Carl and Ellie (including their surnames). This confirms that in 2010, the year that Toy Story 3 is set, Ellie is still alive or at least not long dead. This reinforces the idea that Up is set years later.]
At the beginning of Up, Carl is forced watch naruto shippuden movie 5 to leave his home for a company because the city is being expanded. Think about it. What corporation is guilty of polluting the wrong and ending the local life in the distant future by technological excesses?
Buy-n-Large (BNL), a corporation that controls everything apparently when we come to Wall-E. In the commercial made for the film, 'The History of BNL' it is said that the company came to control up to governments. You get the idea that this corporation has achieved global dominance?
In Finding Nemo have a whole population of marine animals acting together to save a fish caught by humans. The BNL reappears in this universe in a story about a beautiful aquatic world. The worlds are colliding in Finding Nemo. The men are arming themselves against an
