Ritualization
Social biologists believe that some communicative behavior in animals is developed through a process called ritualization. In this process, the purpose of a given behavior changes over time—a behavior that originally had a practical purpose develops into one that communicates a specific message. For example, a certain movement or physical feature might evolve to serve as a signal or warning that other animals will understand. Once a behavior is ritualized, it becomes a form of communication; therefore, if an animal engages in this behavior, other animals will be able to interpret the meaning o the behavior quickly and respond appropriately.

Let’s start with an example you may be familiar with. What’s one thing dogs typically do when they feel threatened? They want to protect themselves. That’s right, they show their teeth. And when we see this, we know this behavior means basically stay away. Now, here’s how this behavior became a recognizable warning. A long long time ago, a dog sensing danger would get read y to bite whatever animal was threatening it. It started by baring its teeth, but the propose of doing it was something very simple: the dog instinctively was making sure that it didn't bite its own lips when it bit the other animal, ok? But what happened, other dogs, other animals, over time, they learned that this teeth baring always came before a dog was going to bite, and so they started to read it as a signal to be careful, to keep away, or risk getting bitten.
This scenario, repeated time after time also led to the dog’s awareness that simply showing its teeth, a lot of the time that was protection enough. What had been a simple preparation to bite had developed into a kind of defense mechanism in and of itself. The dog learned that it did not need to actually attack; but could get the right result by communicating the possibility of attack through showing its teeth. It started to use this behavior as a warning signal.

In the lecture, the professor talks about ritualization which means some animal behaviors change over time, a behavior that had practical purpose can develop into something that can deliver a specific message. And she talks about why dogs show their teeth to warn others. In the very beginning, the purpose of this action was very simple, dogs would bare their teeth so they won’t bite their own lips when engaging in a fight. Over time, other animals have learned that lip- baring means that the dog is ready to attack. And that led the dog to realize that by simply showing it’s teeth, other animals will back off, it’s learned that it did not have to actually attack to get the same results. That’s how dogs begin to use this behavior as a warning signal.
