In biology, a pair bond is the strong affinity that develops in some species between a mating pair, often leading to the production and rearing of young and potentially a lifelong bond. Pair-bonding is a term coined in the 1940s [ 1 ] that is frequently used in sociobiology and evolutionary biology circles.
Filial imprinting is not restricted to non-human animals that are able to follow their parents, however. The filial imprinting of birds was a primary technique used to create the movie Winged Migration (Le Peuple Migrateur), which contains a great deal of footage of migratory birds in flight. The birds imprinted on handlers, who wore yellow ...
After that, it begins bonding with other animals, particularly humans. By imprinting, a dog views a particular creature or person as a significant figure. In fact, anyone who spends considerable ...
Sexual dimorphism in immune function is a common pattern in vertebrates and also in a number of invertebrates. Most often, females are more 'immunocompetent' than males. This trait is not consistent among all animals, but differs depending on taxonomy, with the most female-biased immune systems being found in insects. [129]
Four ways of explaining romantic love have been used to provide a comprehensive biological definition (Bode & Kushnick, 2021): [8] Function: Mate choice, courtship, sex, pair-bonding. Phylogeny: Evolved by co-opting mother-infant bonding mechanisms sometime in the recent evolutionary history of humans.
Imprinting is most often used to describe an early-life bond that can later affect an animal's mate choice.More broadly, the term refers to a rapid and selective learning process that only can occur during certain times in an animal's life.
Lorenz studied instinctive behavior in animals, especially in greylag geese and jackdaws. Working with geese, he investigated the principle of imprinting, the process by which some nidifugous birds (i.e. birds that leave their nest early) bond instinctively with the first moving object that they see within the first hours of hatching. Although ...
Partial imprinting occurs when alleles from both parents are differently expressed rather than complete expression and complete suppression of one parent's allele. [6] Forms of genomic imprinting have been demonstrated in fungi, plants and animals. [7] [8] In 2014, there were about 150 imprinted genes known in mice and about half that in humans ...
