The act of eating one's own offspring, or filial cannibalism, may be an adaptive behaviour for a parent to use as an extra source of food. Parents may eat part of a brood to enhance the parental care of the current brood. Alternatively, parents may eat the whole brood to cut their losses and improve their future reproductive success.

This encompasses behaviors that aid in the evolutionary success of the offspring and parental investment, which is a measure of expenditure (time, energy, etc.) exerted by the parent in an attempt to provide evolutionary benefits to the offspring. [1] Therefore, it is a measure of the benefits versus costs of engaging in the parental behaviors. [1]
Human paternal care is a derived characteristic (evolved in humans or our recent ancestors) and one of the defining characteristics of Homo sapiens. [19] Different aspects of human paternal care (direct, indirect, fostering social or moral development) may have evolved at different points in our history, and together they form a unique suite of ...
Two main types of polyandry exist: simultaneous polyandry and sequential polyandry. An even rarer subtype called cooperative simultaneous polyandry also exists in some species. In simultaneous polyandry, the female will dominate a certain territory which contains several small nests with two or more males, who take care of the offspring.
Alloparental care has many benefits for the young as well as the biological parents of the young. It occurs when there is a high energetic command of the biological parents and the group living of these animals. [4] Alloparenting helps to reduce the stresses on these animals and reduce the overall energetic demands of having offspring. [4]
