Female sex-specific adaptations provide evidence of special design for the purpose of increasing fitness and in turn, reproductive success. [18] For example, mate choice, rape aversion tactics and pregnancy sickness are all female-specific psychological adaptations, identified through empirical research, found to increase genetic contributions ...
In evolutionary biology, the Baldwin effect describes an effect of learned behaviour on evolution. James Mark Baldwin and others suggested that an organism's ability to learn new behaviours (e.g. to acclimatise to a new stressor) will affect its reproductive success and will therefore have an effect on the genetic makeup of its species through ...
The template method is used in frameworks, where each implements the invariant parts of a domain's architecture, while providing hook methods for customization. This is an example of inversion of control. The template method is used for the following reasons. [3] It lets subclasses implement varying behavior (through overriding of the hook ...
"Fixed action pattern" is an ethological term describing an instinctive behavioral sequence that is highly stereotyped and species-characteristic. [1] Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign/key stimulus or releaser.
Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing innate (inborn) elements. The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding ...
Cognitive biology is an emerging science that regards natural cognition as a biological function. [1] It is based on the theoretical assumption that every organism—whether a single cell or multicellular—is continually engaged in systematic acts of cognition coupled with intentional behaviors, i.e., a sensory-motor coupling. [2]
How vs. why questions: Proximate view How an individual organism's structures function Ontogeny (development) Developmental explanations for changes in individuals, from DNA to their current form Mechanism (causation) Mechanistic explanations for how an organism's structures work Ultimate (evolutionary) view
This is an instinct which was seemingly triggered by the similar action sequence involved in retrieving and depositing coins into a bank. Instinctive behaviour is usually automatic and unplanned and is a natural reaction which often is preferred by the animal over learned and unnatural actions. [ 2 ]
