Mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect from predators. [11] Mimicry systems have three basic roles: a mimic, a model, and a dupe.
The form of mimicry in plants that deceives an insect into pseudocopulation is called Pouyannian mimicry after the French lawyer and amateur botanist Maurice-Alexandre Pouyanne. A non-mimetic form of pseudocopulation has been observed in some parthenogenetic, all-female species of lizard. The behaviour does not appear to be necessary to trigger ...
Giant axons of the longfin inshore squid (Doryteuthis pealeii) were crucial for scientists to understand the action potential. [1]Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems.
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
Batesian mimicry is a form of defense that allows a harmless species to mimic the appearance of a toxic, noxious, or harmful species to protect itself from predators. By mimicking the appearance of a harmful species, a predator is less likely to attack the species due to its awareness of the signal of warning color patterns.
Molecular mimicry is, however, only one mechanism by which an autoimmune disease can occur in association with a pathogen. Understanding the mechanisms of molecular mimicry may allow future research to be directed toward uncovering the initiating infectious agent as well as recognizing the self determinant.
Aggressive mimicry stands in semantic contrast with defensive mimicry, where it is the prey that acts as a mimic, with predators being duped. Defensive mimicry includes the well-known Batesian and Müllerian forms of mimicry, where the mimic shares outward characteristics with an aposematic or harmful model. In Batesian mimicry, the mimic is ...
The mechanism, analogous to Batesian mimicry, is found in insects such as the monarch butterfly. In another form, first noted by Edward B. Poulton in 1890, a less vulnerable part of an animal's body resembles a more vulnerable part, for example with deceptive eyespots or a false head that deflects attacks away from the real head, providing an ...
