I did my PhD on social behavior of colored peccaries and only in Zurich Zoo. And I discovered some quite interesting things. For example, there is an inhibition in inbreeding in the species, so the father isn’t mating with the daughters. Or the other thing is helpers. That the elder female siblings actually guard the younger siblings. And this goes so far that they start like dating. And the younger siblings can suckle not only at the mother but at elder siblings, which are not yet fully grown. These are a few of the findings in my PhD.
