In African cichlid fish society, only the dominant male reproduces. But Stanford researchers have found that if the dominant male disappears, a subordinate cichlid can rise to the procreative occasion with stunning speed, having kept its reproductive apparatus idling in low gear for the occasion. Other species, including mammals with similar social structures from mice to rhinos, may use the same approach.
