Neoteny in humans Neoteny in humans Neoteny in humans is the retention of juvenile features well into adulthood. This trend is greatly amplified in humans especially when compared to non-human primates. Adult humans more closely resemble the infants of gorillas and chimpanzees than the adults. Neotenic features of the head include the globular skull thinness of skull bones; the reduction of the brow ridge; the large brain; the flattened and broadened face; the hairless face; hair on (top of) the head; larger eyes; ear shape; small nose; small teeth; and the small maxilla (upper jaw) and mandible (lower jaw).

Regeneration in humans spinal nerves. Researchers, from University of Edinburgh, have succeeded in regenerating a living organ. Regenerated organ is closely resembled with juvenile thymus in terms of architecture and gene expression profile. The thymus gland is one of the first organs to degenerate in normal healthy individuals. Between the years 2005 and 2008 four women with vaginal hypoplasia due to Müllerian agenesis were given regenerated vaginas. Up to eight years after the transplants all organs have normal function and structure. Regeneration in humans Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast
