Cichlids can be protective parents or infanticidal cannibals—studying these extremes could provide new insights into their evolution.



Summary

Cichlids exhibit a wide range of parental behaviors, from highly protective parenting to extreme infanticide and cannibalism. This contrasting behavior makes them ideal for studying the evolution of parental care. By comparing the genetic and behavioral differences between caring and cannibalistic cichlids, researchers hope to understand the factors that drive the evolution of parental strategies. Investigating these extremes can shed light on the environmental pressures, genetic predispositions, and social dynamics that influence whether cichlids nurture or devour their young. This research could offer broader insights into the evolution of parental care across the animal kingdom.
