The classification of central polydactyly is based on the extent of duplication and involves the following three types: Type I is a central duplication, not attached to the adjacent finger by osseous or ligamentous attachments; it frequently does not include bones, joints, cartilage, or tendons.
Young–Madders syndrome, alternatively known as Pseudotrisomy 13 syndrome or holoprosencephaly–polydactyly syndrome, is a genetic disorder resulting from defective and duplicated chromosomes which result in holoprosencephaly, polydactyly, facial malformations and intellectual disability, with a significant variance in the severity of symptoms being seen across known cases.

The polydactyly in these largely aquatic animals is not to be confused with polydactyly in the medical sense, i.e. it was not an anomaly in the sense it was not a congenital condition of having more than the typical number of digits for a given taxon. [1] Rather, it appears to be a result of the early evolution from a limb with a fin rather ...
It can also be caused by polysyndactyly, which is characterized as one normal digit being connected/webbed to an extra digit (polydactyly). Polyonychia can also be acquired, such as after an accident that affected the nail bed causing it to split. This type of polyonychia is just referred to as "post-traumatic split nail" [3]
The just of the section is to say that Polydactyly some-how invalidates evolutionary theory. There is no rule to evolution that prevents Polydactyly nor does it "need" to be explained by evolution. Indeed that fact that Polydactyly can be hereditary gives credence to changes in population over time (which is exactly what evolution is).

A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).
"Forever Young" took parts of Europe by storm, peaking in November 1984 at the number four spot on the top 100 singles list in the band's home country of Germany.
