Regeneration

Regeneration is the ability to re-grow a missing part of the body.[1]

## Comparative Abundance[edit]

Regeneration is seen regularly in fish and amphibians, but less often in higher mammals. Humans can typically regrow the tips of the fingers and toes as adults but nothing else. Deletion of the gene P21 in a knockout mouse model induced the ability to regrow a limb after damage.[2]
