  2. Vestigiality - Wikipedia

    en.wikipedia.org/wiki/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]

  3. Human vestigiality - Wikipedia

    en.wikipedia.org/wiki/Human_vestigiality

    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 structures called vestigial often appear functionless, they may retain lesser functions or develop minor new ones.

    Such is the case in whales, which have small vestigial bones that appear to be remnants of the leg bones of their ancestors which walked on land. [53] Humans also have vestigial structures, including the ear muscles, the wisdom teeth, the appendix, the tail bone, body hair (including goose bumps), and the semilunar fold in the corner of the eye ...

  5. Evidence of common descent - Wikipedia

    en.wikipedia.org/wiki/Evidence_of_common_descent

    Evidence for common descent comes from the existence of vestigial structures. [72] These rudimentary structures are often homologous to structures that correspond in related or ancestral species. A wide range of structures exist such as mutated and non-functioning genes, parts of a flower, muscles, organs, and even behaviors.

  6. Mesonephros - Wikipedia

    en.wikipedia.org/wiki/Mesonephros

    In females, the mesonephros degenerates entirely, though vestigial structures such as Gartner's ducts, the epoophoron, and paroophoron are common. In males, a few of the more caudal tubules will survive and give rise to the efferent ductules of the testis , [ 1 ] the epididymis , vas deferens , seminal vesicle , as well as vestigial structures ...

  7. Gubernaculum - Wikipedia

    en.wikipedia.org/wiki/Gubernaculum

    The gubernaculum has two vestigial remnants in females, the ovarian ligament and the round ligament of the uterus (ligamentum teres uteri) which respectively serve to support the ovaries and uterus in the pelvis. Development of the gubernaculum in female mice overexpressing INSL3 causes descended ovaries and reduced fertility. This ovarian ...
