Our closest invertebrate relative, the humble sea squirt, can regenerate its entire body from just tiny blood vessel fragments, scientists now report.
The entire regeneration process, which in part resembles the early stages of embryonic development, can produce an adult sea squirt in as little as a week.

The finding could illuminate not only the evolutionary origins of regeneration in all organisms, but also subsequent changes to it during vertebrate evolution.
Vertebrates (animals with backbones) such as salamanders are capable of regenerating limbs or tails, and even humans are capable of regenerating portions of skin, lungs and livers.
