African Lion

Every other big cat in this atlas hunts and lives alone. The lion does not. The Smithsonian's National Zoo describes a pride as a group of related females, who do the great majority of the hunting, joined by one or more resident males and by cubs and sub-adults between two and four years old, together numbering anywhere from a handful up to forty individuals. Relatedness runs through the mothers, not the fathers: females typically stay in the pride they were born into for their entire lives, unless a shortage of prey forces them to leave, while young males are pushed out of their birth pride between the ages of two and four, precisely because they are old enough to start competing with the dominant males for the position. What actually sets the size of a pride, the zoo notes, is less about territory and more about how much prey the surrounding land can support, so a pride is really a hunting cooperative sized to its food supply as much as it is a family. Lions once ranged across Africa, into the Middle East and across large parts of Asia. Today the zoo places wild lions almost entirely in Africa, from the southern edge of the Sahara down to northern South Africa, with one narrow exception: a small, separately struggling population of the Asiatic subspecies survives in the Gir Forest of northwest India.

A lion pride can hold up to three resident males, a dozen or more related females, and their young, all of it, per National Geographic Education, built around the females: the lionesses and their cubs are typically all related to one another, which makes the pride fundamentally a maternal line that males join rather than a group either sex owns outright. That structure has a built-in expiration date for every young male born into it. At around two to three years old, males leave the pride, driven out because they are old enough to start competing with the dominant males who currently hold the position, and from that point on a young male has to find a new pride to take over and hunt for himself in the meantime, alone, without the cooperative hunting structure he grew up inside. It is a hard transition by design rather than by accident: a pride that let its own sons stay and mature into rivals would eventually fracture from the inside, so the same relatedness that makes a pride stable also makes it, at a certain age, actively unlivable for its own male members. The departure is not punishment. It is closer to a scheduled event built into how the social structure holds together at all.
