In the context of human evolution, vestigiality involves those traits occurring in humans that have lost all or most of their original function through ...
A broken finger or finger fracture is a common type of bone fracture, affecting a finger. [1] Symptoms may include pain, swelling, tenderness, bruising, deformity and reduced ability to move the finger.

Vestigiality. In humans, the vermiform appendix is sometimes called a vestigial structure as it has lost much of its ancestral digestive function. 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]
Psychological adaptations are those adaptive traits that we consider cognitive or behavioral. These can include conscious social strategies, subconscious emotional responses (guilt, fear, etc.), or the most innate instincts. Evolutionary psychologists consider a number of factors in what determines a psychological adaptation, such as ...
Brachydactyly type D, also known as short thumb, [3][1] stub thumb, [5][6] or clubbed thumb, [5][6] is a genetic trait clinically recognised by a thumb being relatively short and round with an accompanying wider nail bed.
