Most of us have seen the Lion King as kids. The movie got its new and modern version lately. Disney has made a great story, but also an educational story.
How do lion prides work? And what is the lion kingdom? All of the lionesses in the pride are related. Female cubs typically stay with the group as they age, while young males eventually leave and establish their own prides by taking over a group headed by another male.
There is one dominant male in the pride. And when the dominant male is killed or driven off by one of these bachelors, a father may be replaced by his son. Inbreeding is common in lion prides, as there is no way of preventing it. There is also no way to ensure outcrossing.
With that in mind, this nature documentary explains exactly how the kingdom of the lion works.
