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.

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 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 book explores how women’s biology shaped human history and culture. [1] One claim in the book is that when it comes to biological and medical research and clinical drug trials women's bodies have long been overlooked because males have fewer "complicating" factors such as the estrous cycle .
[7] [8] Other authors have written similar books recently, such as Jerry Coyne's Why Evolution is True which Dawkins highly recommends. [9] The book is dedicated to Dawkins' technical assistant and web designer Josh Timonen (left). Dawkins's literary agent John Brockman promoted the book to publishers under the working title Only a Theory.
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 ...
