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 ...
In the foregoing examples the vestigiality is generally the (sometimes incidental) result of adaptive evolution. However, there are many examples of vestigiality as the product of drastic mutation, and such vestigiality is usually harmful or counter-adaptive. One of the earliest documented examples was that of vestigial wings in Drosophila. [21]
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 ...

Cognitive archaeology is a theoretical perspective in archaeology that focuses on the ancient mind. It is divided into two main groups: evolutionary cognitive archaeology (ECA), which seeks to understand human cognitive evolution from the material record, and ideational cognitive archaeology (ICA), which focuses on the symbolic structures discernable in or inferable from past material culture.
For example, Africans are quite varied to begin with, but some of them have somewhat smaller eye sockets, which may give the impression that the plica semilunaris is larger or may provoke it to develop larger as a byproduct that has no relation with more-or-less vestigiality whatsoever.
An example of trait psychology development (stages): Singling out the types of love as psychology of traits. In the Antique time, the typology of the kinds of love was very popular. These kinds of love comprised: Eros – a passionate physical and emotional love based on aesthetic enjoyment; stereotype of romantic love
