Some scientists are researching how lizards regenerate their tails. Salamanders and fish can regenerate too, but they do it differently from lizards. Their growth focuses at the tip while the lizard’s growth is throughout the tail. This isn’t the only reason researchers are focusing on lizards. They are more closely related to humans than the others. Mammals share 302 of the 326 genes activated by lizards to regenerate.
Scientists will continue with this research so that one day we may be able to regrow important body tissue and parts. To learn more, read their findings in the PLOS ONE journal.
