A molecular genetic analysis of kinship and cooperation in African lions

Paternity analysis of African lions reveals that male reproductive success becomes increasingly skewed as coalition size increases and the tendency to form coalitions with non-relatives drops sharply with increasing coalition size. Thus, males only act as non-reproductive "helpers" in coal...
