The muscles connected to the ears of a human do not develop enough to have the same mobility allowed to monkeys. Arrows show the vestigial structure called Darwin's tubercle. In the context of human evolution, vestigiality involves those traits occurring in humans that have lost all or most of their original function through evolution. Although ...
Evolutionary psychology proposes that the human psychology consists primarily of psychological adaptations, [2] which is opposed by the tabula rasa or blank slate model of human psychology. Early behaviourists, like B.F. Skinner , tended to the blank slate model and argued that innate behaviors and instincts were few, some behaviourists ...
Many examples of these are vestigial in other primates and related animals, whereas other examples are still highly developed. The human caecum is vestigial, as often is the case in omnivores, being reduced to a single chamber receiving the content of the ileum into the colon.
In evolutionary biology, a spandrel is a phenotypic trait that is a byproduct of the evolution of some other characteristic, rather than a direct product of adaptive selection. Stephen Jay Gould and Richard Lewontin brought the term into biology in their 1979 paper " The Spandrels of San Marco and the Panglossian Paradigm: A Critique of the ...
Greater likelihood of recalling recent, nearby, or otherwise immediately available examples, and the imputation of importance to those examples over others. Bizarreness effect: Bizarre material is better remembered than common material. Boundary extension: Remembering the background of an image as being larger or more expansive than the ...

A vestigial response or vestigial reflex in a species is a response that has lost its original function. In humans, vestigial responses include ear perking, goose bumps and the hypnic jerk . In humans
In such a case, a shift in the time a trait is allowed to develop before it is fixed can bring forth an ancestral phenotype. [5] Atavisms are often seen as evidence of evolution. [6] In social sciences, atavism is the tendency of reversion: for example, people in the modern era reverting to the ways of thinking and acting of a former time.
