Lone wolf (trait)
A lone wolf is an animal or person that generally lives or spends time alone instead of with a group. The term originates from wolf behavior. Normally a pack animal, wolves that have left or been excluded from their pack are described as lone wolves.
In the animal kingdom, lone wolves are typically older female wolves driven from the pack, perhaps by the breeding male, or young adults in search of new territory. Many female wolves between the ages of one to four years old leave their family to search for a pack of their own. This has the effect of preventing inbreeding as there is typically only one breeding pair in a wolf pack. Very few wolves will simply remain lone wolves; as such, these lone wolves may be stronger, more aggressive and far more dangerous than the average wolf that is a member of a pack. However, lone wolves have difficulty hunting, as wolves' favorite prey, large ungulates, are troublesome for a single wolf to bring down alone. Instead, lone wolves will generally hunt smaller animals and scavenge carrion.
In literature, lone wolves are aloof and emotionally unable or unwilling to directly interact with other characters in the story. A stereotypical lone wolf will be dark or serious in personality; they are often taciturn and distinguished by their reserved nature. A lone wolf often has undergone some emotional trauma which separates them from the crowd.
Lone wolf also are described as someone who lives alone and only survives through hunting, fishing, harvest and lumbering with rudimentary weapons or tools, without basic services like water treatment or electricity and very limited telecommunications connection. This people has often useful breeds of dogs to hunts like Beagles.
