So I was watching Night on Earth on Netflix and wondered: how is it that polar bears (and other mammals like elephants and lions) know when to leave their mother?
In: Biology
In most mammalian species there is a period of time where the child is dependent upon the parent. After such period of time the child then knows enough to survive on its own or to at least not immediately die without its mother’s care. When such condition is met, inevitably there will come a day whenever the child realizes that (s)he is tired of all of the bitching and leaves.
