parental care
Quick Summary
Parental care involves the protection and nurturing of offspring to ensure their healthy development into adulthood. This process is costly for parents, as it requires significant investment of time and resources, often at the expense of their own future reproductive opportunities. However, the primary benefit is increased offspring survival and future reproductive success.12
Parental care can take many forms, from guarding eggs to feeding and protecting young for extended periods. In many species, females bear the primary responsibility for care, though biparental care and male-only care also occur. The decision to provide care is influenced by a complex interplay of costs and benefits, including the sex of the parent, paternity certainty, and physiological constraints. For instance, mammals nourish their young with milk produced by mammary glands.234
