It derives from the Greek term mimetikos, "imitative", in turn from mimetos, the verbal adjective of mimeisthai, "to imitate". [1] "Mimicry" was first used in zoology by the English entomologists William Kirby and William Spence in 1823. [2] [3] Originally used to describe people, "mimetic" was used in zoology from 1851. [1]
[1] [2] This naturalistic explanation fitted well with the recent account of evolution by Wallace and Charles Darwin , as outlined in his famous 1859 book The Origin of Species . Because the Darwinian explanation required no supernatural forces, it met with considerable criticism from anti-evolutionists , both in academic circles and in the ...
The term bionic then became associated with "the use of electronically operated artificial body parts" and "having ordinary human powers increased by or as if by the aid of such devices". [14] Because the term bionic took on the implication of supernatural strength, the scientific community in English speaking countries largely abandoned it. [12]
Imitation and imitative behaviors do not manifest ubiquitously and evenly in all human individuals; some individuals rely more on imitated information than others. [64] Although imitation is very useful when it comes to cognitive learning with toddlers, research has shown that there are some gender and age differences when it comes to imitation.
Imaginary cladogram. [2] The yellow mask is a plesiomorphy for each living masked species, because it is ancestral. [2] It is also a symplesiomorphy for them. But for the four living species as a whole, it is an apomorphy because it is not ancestral for all of them. The yellow tail is a plesiomorphy and symplesiomorphy for all living species.
Echopraxia is a typical symptom of Tourette syndrome but causes are not well elucidated. [1]Frontal lobe animation. One theoretical cause subject to ongoing debate surrounds the role of the mirror neuron system (MNS), a group of neurons in the inferior frontal gyrus (F5 region) of the brain that may influence imitative behaviors, [1] but no widely accepted neural or computational models have ...
There is a strong evolutionary pressure for prey animals to avoid predators through camouflage, and for predators to be able to detect camouflaged prey. There can be a self-perpetuating coevolution, in the shape of an evolutionary arms race, between the perceptive abilities of animals attempting to detect the cryptic animal and the cryptic characteristics of the hiding species.
These features normally disappear in later development, but it may not happen if the animal has an atavism. [1] [2] In biology, an atavism is a modification of a biological structure whereby an ancestral genetic trait reappears after having been lost through evolutionary change in previous generations. [3]
