Why are lions social animals?

[Pantherinae]

those studies where taken on lionesses, when they did The same to male lions, they found out a male lion would come to challenge The invaders even if he was outnumberd 3:1

Karen McComb was the one who measured the responses of one to seven Serengeti females to the recorded roars of one or three females. A roar is a territorial display, so if a stranger roars in the middle of your territory, it’s like coming home and finding a stranger sitting comfortably in your living room. The females responded according to the odds: if lone females heard the roar of a single female, they would sit tight and try to recruit their distant pridemates; but groups of three females would immediately approach the loudspeaker. When exposed to a roaring trio, a real trio would again try to recruit help; but a quintet would quickly approach. As long as “us” outnumbered “them” by at least two individuals, “we” would move to oust the invaders.

In a set of experiments to resident males, Jon Grinnell found a similar sense of “numeracy” but the males sometimes approached even when outnumbered three to one—probably because male lions only have a brief opportunity to father offspring and are more likely to be suicidal in protecting their pride.
