Albinism in humans Albinism in humans Albinism is a congenital disorder characterized in humans by the complete or partial absence of pigment in the skin, hair and eyes. Albinism is associated with a number of vision defects, such as photophobia, nystagmus, and amblyopia. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers. In rare cases such as Chédiak–Higashi syndrome, albinism may be associated with deficiencies in the transportation of melanin granules. This also affects essential granules present in immune cells leading to increased susceptibility to infection. Albinism results from inheritance of recessive gene alleles and is known to affect
Muscular evolution in humans but what was gained was the ability to hold a club or throw a spear and use the other free hand for another task. This adaptation also helped humans stand up straight with locked knees for longer periods of time. The plantaris muscle in the foot which helped our ancestors grab and manipulate objects like chimps do, has adapted to its new evolutionary role appropriately, becoming so underdeveloped that it cannot grip or grab anything, the foot has grown more elongated as a result and now 9% of humans are born without it. Homo sapiens benefitted by becoming a better
