Little Biology: Why can’t I regrow my arm?

Why can some animals regrow limbs while others can’t? Will understanding regeneration in other vertebrates help us regrow arms one day? Our intern team has taken over the channel to talk about one of their favorite biology topics, limb regeneration! In the episode, Dayna and Kyle break down the mechanisms of regeneration and discuss why some animals can regrow organs and limbs, and why the evolutionary paths of other animals may have led to alternative responses to limb loss. Thanks for listening! This episode of Little Biology was written and presented by Dayna De La Cruz and Kyle Smith. If you enjoyed it, please give them a hand!
