Homology in psychology, as in biology, refers to a relationship between characteristics that reflects the characteristics' origins in either evolution or development. Homologous behaviors can theoretically be of at least two different varieties. [ 1 ]
Spider behavior refers to the range of behaviors and activities performed by spiders. Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom . They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms [ 1 ] which is reflected in their ...
A neuron (green and white) in an insect brain (blue) Insect cognition describes the mental capacities and study of those capacities in insects. The field developed from comparative psychology where early studies focused more on animal behavior. [1] Researchers have examined insect cognition in bees, fruit flies, and wasps. [2] [3]
The ethological concept of species-typical behavior is based on the premise that certain behavioral similarities are shared by almost all members of a species. [1] Some of these behaviors are unique to certain species, but to be 'species-typical' they do not have to be unique, they simply have to be characteristic of that species.
Secondary homology is implied by parsimony analysis, where a character state that arises only once on a tree is taken to be homologous. [20] [21] As implied in this definition, many cladists consider secondary homology to be synonymous with synapomorphy, a shared derived character or trait state that distinguishes a clade from other organisms.
A formula called the encephalization quotient (EQ) expresses a relationship between brain and body size; it was developed by H.J. Jerison in the late 1960s. [158] When the encephalization quotient is plotted as a curve, an animal with an EQ above the curve is expected to show more cognitive ability than the average animal of its size, whereas ...
“Spider Webbing is a term used to describe a complex network of manipulative behaviours woven over time, which can entangle individuals in a tumultuous and unhealthy relationship, often leaving ...
Silk: spiders, silk moths, larval caddis flies, and the weaver ant all produce silken threads. [145] The praying mantis body type – raptorial forelimb, prehensile neck, and extraordinary snatching speed - has evolved not only in mantises but also independently in neuropteran insects Mantispidae.
