Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...
A defining feature of aggression is the intent or motivation to harm. For a behavior to be considered an aggressive act, the individual committing the behavior must intend harm. In other words, if they inflict harm on another without that specific intent, it is not considered aggression. [15] Aggression can occur in a variety of situations.
Though other animals may not possess what humans may perceive as moral behavior, all social animals have had to modify or restrain their behaviors for group living to be worthwhile. Typical examples of behavioral modification can be found in the societies of ants, bees and termites. Ant colonies may possess millions of individuals. E. O.
The first occurrence of the term "evolutionary mismatch" may have been in a paper by Jack E. Riggs published in the Journal of Clinical Epidemiology in 1993. [7] In the years to follow, the term evolutionary mismatch has become widely used to describe biological maladaptations in a wide range of disciplines.
The social behavior is believed to have evolved in a fashion similar to other types of nonbehavioral adaptations, such as a coat of fur, or the sense of smell. Individual genetic advantage fails to explain certain social behaviors as a result of gene-centred selection. E.O. Wilson argued that evolution may also act upon groups. [14]
Counterproductive work behavior (CWB) is employee's behavior that goes against the legitimate interests of an organization. [1] This behavior can harm the organization, other people within it, and other people and organizations outside it, including employers, other employees, suppliers, clients, patients and citizens.
Neuroplasticity is seen as an adaptation that helps humans to adapt to new stimuli, especially through motor functions in musically inclined people, as well as several other hand-eye coordination activities. An example of maladaptation in neuroplasticity within the evolution of the brain is phantom pain in individuals who have lost limbs. While ...
