Parental care is a behavioural and evolutionary strategy adopted by some animals, involving a parental investment being made to the evolutionary fitness of offspring. Patterns of parental care are widespread and highly diverse across the animal kingdom. [1] There is great variation in different animal groups in terms of how parents care for ...
Paternal care. In biology, paternal care is parental investment provided by a male to his own offspring. It is a complex social behaviour in vertebrates associated with animal mating systems, life history traits, and ecology. [1] Paternal care may be provided in concert with the mother (biparental care) or, more rarely, by the male alone (so ...
Parental care refers to the level of investment provided by the mother and the father to ensure development and survival of their offspring. In most birds, parents invest profoundly in their offspring as a mutual effort, making a majority of them socially monogamous for the duration of the breeding season. This happens regardless of whether ...
Maternal behavior in vertebrates. Vertebrate maternal behavior is a form of parental care that is specifically given to young animals by their mother in order to ensure the survival of the young. [1] Parental care is a form of altruism, which means that the behaviors involved often require a sacrifice that could put their own survival at risk. [1]
A human mother feeding her child. Parental investment, in evolutionary biology and evolutionary psychology, is any parental expenditure (e.g. time, energy, resources) that benefits offspring. [1][2] Parental investment may be performed by both males and females (biparental care), females alone (exclusive maternal care) or males alone (exclusive ...
Matriphagy is one of the most extreme forms of parental care observed in the animal kingdom. However, in some species such as the Funnel-web spider Coelotes terrestris , matriphagy is only observed under certain conditions and extended maternal protection is the main method by which offspring receive care.
The triune brain is a model of the evolution of the vertebrate forebrain and behavior, proposed by the American physician and neuroscientist Paul D. MacLean in the 1960s. The triune brain consists of the reptilian complex (basal ganglia), the paleomammalian complex (limbic system), and the neomammalian complex (neocortex), viewed each as ...
The evolution for semelparity in both sexes has occurred many times in plants, invertebrates, and fish. It is rare in mammals because mammals have obligate maternal care due to internal fertilization and incubation of offspring and nursing young after birth, which requires high maternal survival rate after fertilization and offspring weaning ...
