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 ...
Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. [1] Assessment of the vestigiality must generally rely on comparison with homologous features in related species.
This phenomenon is an automatic-response mechanism that activates even before a human becomes consciously aware that a startling, unexpected or unknown sound has been "heard". [ 2 ] That this vestigial response occurs even before becoming consciously aware of a startling noise would explain why the function of ear-perking had evolved in animals.
The young Robert Ernst Eduard Wiedersheim, probably in early 1874 by Alfredo Noack in Genoa. [1]Robert Ernst Eduard Wiedersheim (21 April 1848 – 12 July 1923) was a German anatomist who is famous for publishing a list of 86 "vestigial organs" in his book The Structure of Man: An Index to His Past History.
This also seems somewhat less dubious, both as a human-specific vestigiality, and the the variation seems to be less possibly accidental, but actually representing different degrees of vestigiality (which is not to place any particular continent population at any hierarchical "kickass" or "loser" place on the "evolutionary scale", not even as ...

Vietnam's ethnic mosaic results from the peopling process in which various peoples came and settled the territory, leading to the modern state of Vietnam by many stages, often separated by thousands of years over a duration of tens of thousands of years. Vietnam's entire history, thus, is an embroidery of polyethnicity. [14]
The Vietnamese people (Vietnamese: người Việt , lit. ' Việt people ' or ' Việt humans ') or the Kinh people (Vietnamese: người Kinh , lit. 'Metropolitan people'), also recognized as the Viet people [67] or the Viets, are a Southeast Asian ethnic group native to modern-day northern Vietnam and southern China who speak Vietnamese, the most widely spoken Austroasiatic language.
